It's not a coup if you stay in power illegally, it's a self-coup. 2020 was a coup attempt because Trump gave up power and then tried to give it back. He's not going to make that same mistake again. He'll just attempt to stay in power via self-coup.
Unlike coup's which are distinct events, self-coup's are usually shades of grey. They happen through democratic backsliding, which usually consists of a large number of small events. I'm sure we'll see some more before the next election. Will it be enough so that the US is as bad as Russia or Turkey? No. Will it be enough to keep Trump in power illegally? Perhaps.
You'd have to overthrow parts of the US government to keep power for a 3rd term I'd still call that a coup even if it's coming from inside the house. Coups rarely come from entirely external forces, the military basically always has a major role in deciding if a coup is successful even if it's just staying neutral and seeing where the chips fall.
Trump has already "overthrown" the executive on every major part of the US government using executive, judicial and legislative processes. Sometimes this has been illegal (ex FCC). Nobody calls it a coup.
