Hard to say, but doubtful. At one point Trump referred to Snowden as a traitor. Then as president (the first time around) he mulled the prospects of a pardon, but of course never went through with it.
I think this is possible because of current political situation and war in that region, they could potentially use Snowden for some negotiation deals since he is still located in Russia I think.
This is just my wild speculation, but if Biden can pardon his son and whole family... them anything can happen in 2025.
