No. The power of the pardon is explicitly granted to the President in the text of the Constitution, and it provides no mechanism for reversing such pardons. It’s meant to be a check against unjust laws and/or corrupt courts, and presidents who would corruptly abuse the power for their own profit are supposed to be removed from office via impeachment—but as we’ve seen, Congress won’t even remove a president who orchestrates a mob attack against themselves as part of a scheme to overthrow an election.

Go read the actual text of the US Constitution . The answer is a quirky technical “well, theoretically yes but practically no.”

constitution.congress.gov/browse/…/clause-1/

The President … shall have Power to grant Reprieves and Pardons for Offences against the United States, except in Cases of Impeachment.

That last emphasized line means that if the US Congress were to impeach and remove a president for bribery or a criminal conspiracy, they could also negate any pardons given to POTUS’s collaborators.

Of course, since no US President has ever been removed from office by congress’s impeachment power, and it’s uncertain if a post-term impeachment and conviction would itself pass the inevitable SCOTUS appeal, this is even less likely than the US Congress awarding a no-majoroty electoral collage vote to the other major party.

I thought the intent behind that wasn’t to revoke previous pardons, but was to prevent a president from pardoning themselves in an impeachment trial.

That's the neat part, it's worded such that it could go either way. With the current makeup of the court, impeachment proceedings would have to start with the 6 first, and then flow back to the executive if we wanted anything to actually stick.
