Is it because at absolute zero you would know with certainty the momentum and the position of the particle? Or is there another reason? Would we ever be able to overcome the Heisenberg uncertainty principle?

Essentially yes, but that just pushes the question back to why the HUP exists, so it’s not really an answer. But at incredibly tiny scales (the “quantum level”), things don’t have a definite position. Nothing at that level is in one place the way we think of “place” at the everyday level. Absolute zero is defined as the complete cessation of motion – no vibration, no jitters, no movement at all. That is simply not possible at the tiniest scales.
