I do see the possibility, but if it is true then the only way to stop it is armed insurrection against a tyrant. Trump would have to dismantle the courts, blatantly violate the constitution, and fundamentally alter the government. The military would have to go along with it too. The problem is that you cannot make a preemptive strike or you give Trump a casus belli to do just that. Whomever acts first loses, and it should be the administration commiting unambitious treason first if you want to stop it. Until then, you need to keep working through the established legal system.
I still don't think Trump has the personal or political charisma to line up every hole in the swiss cheese of constitutional, legal, moral, and cultural protections to pull it off, but I'll be prepared to eat crow if he does succeed in overthrowing the government and becoming a dictator.
That would require the federal election committee to violate the constitution by putting him on the ballot, then the same for every State government. This is an order of magnitude beyond the attempts to keep him off the ballots for Jan 6, as he was never convicted of or tried for it. The Supreme Court would need to destroy the constitution to rule favorably on it, and thus remove all their own power as the third branch of government.
The US is not yet as corrupt as the CCP or Russia, and Trump doesn't have the political and personal capital of Xi or Putin to rewrite the constitution to allow more/unlimited presidential terms.
