I have seen topics which mention time dilation in Hinduism but I am specifically looking for travelling back in time.
No, there cannot be such reference in reliable scripture/sources of backward time travel.
Because, it's not possible to change past even in theory. Refer Grandfather paradox, which is a rational source to understand "why backward time travelling is not possible".
Clarification: As per the wordings of the question, it infers about asking "physical body's time travelling in past". My answer reiterates that the reliable scriptural sources usually may not have references to impossible things (e.g. 1 + 1 = 3)
Now, there is a certain yogic knowledge of memorizing events of earlier [or upcoming] births as well. Many people call such special kind of "remembering" as "subtle body travelling in past". Such yogic ability has been reportedly gained by many people throughout the world in ancient & modern times.
