The answer to your question is Yes.
This is what Lord Shiva says in KulArnava Tantram's 9th chapter:
Aswamedhayutenapi BrahmahatyAtena Cha | PunyapApairna Lipyante
YeshAm Brahma Hridi StithAm ||
Those who have realized self (or Brahman) are neither affected by the
performance of thousands of Aswamedha yajna nor by the sins of killing
In this verse, performance of Aswamedha is taken as an example of an act of high merit (punya) and killing Brahmins is taken as an example of an act of great demerit (papa).
One, who has attained self, is unaffected by both. This is the purport of the verse.
Tattvanishtashya Cha KarmAni PunyApunyAni Samkshyam | PrayAnti Naiva
Lipyante KriyamAnAni VA Punaha ||
The person who has attained tattva gyana (or the knowledge of self)
has all his karmas (both good and bad) destroyed. And he
is not affected even if he performs those karmas again.
KulArnava Tantram 9-128.
The Shiva Samhita also says the same thing:
He who contemplates on this [the lotus at the Ajna Chakra or on the
Itara Shiva linga that is situated there], standing or walking,
sleeping or waking, is not touched by sins, even it were possible
for him to do the sinful works.
