Yes. In the context of tantra and Yoga, there are various techniques to get complete enlightenment and get liberated in a single lifetime. Past life impressions or karma are often stored in the astral body (shukshma sharira) that can be burnt in a single lifetime to get enlightenment and quick liberation.
The goal of Raja Yoga is Kaivalya Samadhi. Here the goal of the yogi is to silence and still the mind from the present as well as previous life accumulation of life impressions of Pain and Pleasure. Once Kaivalya Samadhi is mastered, all the past life impressions are destroyed and soul gets liberated already while living (Jivanmukta).
- The resolution in the inverse order of the qualities, perfect of any motive of action for the Purusa, is Kaivalya, or it is the
establishment of the power of knowledge in its own nature.
~ Yoga Sutras of Patanjali, IV.
Nature’s task is done, this unselfish
task which our sweet nurse Nature had imposed upon herself. As it
were, she gently took the self-forgetting soul by the hand, and showed
him all the experiences in the universe, all manifestations, bringing
him higher and higher through various bodies, till his glory came
back, and he remembered his own nature. Then the kind mother went back
the way she came, for others who have also lost their way in the
trackless desert of life. And thus she is working, without beginning
and without end. And thus through pleasure and pain, through good and
evil, the infinite river of souls is flowing into the ocean of
perfection, of self-realisation.
Glory unto those who have realised their own nature. May their
blessings be on us all!
Commentary by Swami Vivekananda. Raja Yoga.
Those who feel ardently for Self-realisation, who have burning
Vairagya, attain at once to the state of Asamprajnata Samadhi. Burning
Vairagya and intense Sadhana are needed. Then the fruit is near at
hand. According to the degree of Vairagya and degree of Sadhana, there
are nine stages or steps wherein Yogis halt. The fruit of Samprajnata
Samadhi is Asamprajnata Samadhi, and the fruit of Asamprajnata Samadhi
is Kaivalya or absolute independence [*].
*Absolute Independence here refers to Liberation

In the context of tantra, there is a wide library of methods to achieve the goal of Raja Yoga very quickly. The principal ones include Kundalini Yoga, where the goal is to artificially clean the passages of nadis (through prana), balance chakras, and then arouse the Kundalini to move upward and unite with Sahasrara chakra. Again, there are hundreds of sub-methods to achieve this - Hatha Yoga, Kriya Yoga (of Mahavatar Baba Ji's), Mantra Yoga, Shaktipath initiation, Shava Sadhana, etc.
- Hatha Yoga

- Kriya Yoga
Kriya Yoga speeds up our spiritual growth in several ways. One of them
is the rapid burning up of past bad karma. According to our Kriya
Gurus, kriya helps to increase the current of energy in the astral
spine. This strong current carries along with it the vrittis of past
karma — much like a river in flood will sweep away all the stagnant
eddies and whirlpools, and carry all the old debris to the ocean.

- Shaktipath Initiation
In higher tantras, especially traditions of Nathas and Kashmiri Shivaism, there is a way in which a Siddha guru is supposed to impart Kundalini Awakening to the disciple via touching chakras in the body. This leads to temporary awakening of Kundalini in disciple and burning of Karma and it returns back to normal. Depending upon the capacity of the disciple, different intensities of initiation is given to them.
Shaktipata (Sanskrit: शक्तिपात, romanized: śaktipāta) or Shaktipat
refers in Hinduism to the transmission (or conferring) of spiritual
energy upon one person by another or directly from the deity.
Shaktipata can be transmitted with a sacred word or mantra, or by a
look, thought or touch – the last usually to the ajna chakra or agya
chakra or third eye of the recipient.
Shaktipata is considered an act of grace (Anugraha) on the part of the
guru or the divine. It cannot be imposed by force, nor can a receiver
make it happen. The very consciousness of the god or guru is held
to enter into the Self of the disciple, constituting an initiation
into the school or the spiritual family (kula) of the guru. It is
held that shaktipata can be transmitted in person or at a distance,
through an object such as a flower or fruit.

While it is possible that a guru can awaken the kundalini of a disciple from a very large distance (even almost from a distance of a different part of the world), the intensity of the feeling is very high, hence a guru nearby physically available is highly recommended in case of emergency.
The purpose to do shava sadhana varies from person to person. An aim
of shava sadhana is to unite the Kundalini with Param Shiva. From a
yogic or Tantric point of view, it signifies detachment from the
physical world, and uniting with the Absolute, identified with the
male god Shiva, the Divine Mother Shakti or the abstract Brahman. The
detachment leads to freedom from Samsara (the cycle of birth, death
and reincarnation) and the adept goes beyond the orthodox concepts of
purity and impurity; auspiciousness and inauspiciousness.
Wikipedia.Shava Sadhana. Date Accessed: 19-01-24
Shava Sadhana is a left-handed tantric practice where a corpse from a cremation ground is awakened temporarily to invoke deities, demons while raising kundalini. It is a highly tamsic practice and should not be performed.
Although there are hundreds of ways to do the same, here are some brief different approaches to the goal of Raja Yoga - Kaivalya Samadhi.
Dangers of Kundalini Awakening
The opening of the chakras has been the subject of a tremendous amount
of focus in the yoga literature, with emphasis on the awakening of the
kundalini energy at the base of the spine, and the rising up of this
energy through each of the chakras up to the crown of the head. The
dangers associated with this process have also been described, as a
sudden opening of one of the lower chakras can lead to serious
psychological and physical imbalances and dangers, particularly if
there is not a trusted and experienced guide to help one manage the

In contrast to this, Sri Aurobindo (a yogi and philosopher from India)
believed that kundalini in itself would not induce psychosis in a
previously healthy individual, but that a constitutionally weak
nervous system, already predisposed to emotional problems, might
decompensate under the stress of kundalini awakening (especially if
proper precautions are not observed) . Similarly, a study reported
two cases who had been diagnosed as schizophrenia patients but had
actually been going through a spiritual crisis (a form of identity
crisis where an individual experiences drastic changes to their
meaning system (i.e., their unique purposes, goals, values, attitude
and beliefs, identity, and focus) typically because of a spontaneous
spiritual experience.) [7,8].

She ascribed the vibration to some eternal force and considered
herself to be its passive recipient. She also felt that people around
her are talking about her, though others repeatedly refuted that, and
was hearing clear voices, in an awake state, telling her to follow
orders in her day-to-day activities. Her sleep pattern was disturbed;
she would frequently get up at night and would often be found doing
pranayama and meditation.
Over a month, she also expressed to have experienced eternal
enlightenment and would feel that all materialistic things, including
a person’s basic needs of hunger and thirst, are immaterial to them.
Initially, her family members also believed these experiences to be an
outcome of her yoga practices but were later concerned with a gradual
change in her previous self and social and biological function. This
change in the patient was not seen as deviance but as an impact of
yoga practice until she stopped eating, speaking, and interacting with
others and was found frozen in sustained postures, requiring medical

In summary, there are clear indications of - schizophrenia, psychosis, and other mental disorders at very advanced stages and levels that almost become untreatable for a lot of people throughout their lives. The sort of disability is via improper kundalini awakening or using violent and unstable methods often leads to problems that aren't even properly understood by medical sciences.
Yes, there are methods to burn past life impressions, but could be harmful and very dangerous if done very quickly and wrong without the aid of a guru. It is always recommended to have slower and more stable progress toward these.
