There is no viable Constitutional path for Trump to remain President, even if every single Republican voted for it. On a purely theoretical level, the only path for Trump would be if a number of Democratic members of Congress joined forces with Republicans to oppose certification, and (despite GordonGekko's hot take proposition) that idea does not have a snowball's chance in hades of reaching culmination.

"Specifically, likely Speaker Nancy
Pelosi (D-Calif.) is proposing the House adopt pay-as-you-go (paygo) rules that require all new spending be offset with either budget cuts or tax increases.These rules would also prohibit any new taxes on the bottom 80 percent of the income distribution. Overturning the rules would require a 60 percent supermajority, which means that a substantial number of Republicans would have to be pulled along to get passage.
To see why this is such a poor idea, it’s only necessary to think of many of the proposals that Democrats floated in the recent election.
There is considerable support among Democrats for "Medicare for All," extending the Medicare program to the whole population. While many do not interpret this as meaning an immediate extension of Medicare to everyone, even lowering the qualifying age to 55 or 60 will mean additional spending.
Under Pelosi’s pay-go rule, this extension
would be prohibited unless it was coupled with offsetting budget cuts and/or taxes on the top 20 percent."

Pelosi is pushing a plan that, on it's face, sounds fiscally simple and practical to the average American citizen ( i.e. only buy something if you trade something else that equalizes it) but would kill Green New Deal ( which is not unreasonable since that's financially impossible) but also Medicare For All. Her concern, and it's a valid one, is that AOC will grow her current 8 voter block in the HOR and expand that in the 2022 election cycle. AOC endorsing young Progressive digital natives is a pin from the Pope. She can generate to what amounts of unpaid media coverage in the millions for someone drastically far down the political totem pole who just can't generate that kind of money and whom the DNC cabal won't support.
Even though most of the DNC actually supports M4A, because of Joint Finance Agreements weaponized by the Obama administration and then the Clinton 2016 run, everyone down the ticket outside the Progressives are financially dependent on the Party apparatus and the Obama/Biden loyalists who control the purse strings. This is why Pete Buttigieg dropped out of the primaries when he did and pushed Medicare For All Who Want It when it offered him no true political advantage to do so. The casino had the poker table stacked against him, so he cash in his chips for a future payout. Neutralizing Buttigieg kept him away from flipping to the Progressives/Socialists faction, whom they desperately needed for AOC to make an eventual POTUS run. Buttigieg is the DNC's version of Nikki Haley (Think prime Charles Woodson on the Packers defense, creating more answers than questions and patching over multiple flaws everywhere else)
If AOC wants M4A in the next decade, she will either have to trade something to the Republicans en masse for it or become POTUS. Either way, the internal fight inside her own Party is assured. The Obama/Biden and Pelosi/Newsom factions want Miss GND cancelled. They want to prop up Obamacare at all costs.
It's a long shot, but if I was in Trump's shoes, I'd offer AOC the deal. Your voting block in the HOR and the Sanders/Warren votes in the Senate for a guarantee of M4A. I'd see what happens.
