There’s lots of good explanations of what the US Constitution allows… but they don’t actually matter!
No matter which branch of government (executive, judicial, or legislature) have the power to “do away with pardons” the same has the power to bring them back.
In parliamentary systems this is called the “supremacy of parliament”.
So even if Biden could issue an executive order to stop pardons then Trump can just executive order them back.
