is there any scenario in which trump could remain in office?
The traditionally red states of Pennsylvania, Georgia and Arizona could go the "faithless elector" route, where their electors give Trump the win, even though Biden wins the popular vote in their states.
About 32 states have laws binding their electors to vote according to the popular vote count; those 3 states are not among them, and would given a 47-point swing, putting Trump in the lead and Biden behind. Trump has already asked states like Georgia to do just that.
USA Today has an article outlining why this the case:

The Founders distrusted the common person and allowed Electors to change their vote to keep demagogues likes Trump out; obviously, the Electoral College failed it's intended purpose.
But this is one situation where Trump could legally retain office.
