I would say that most Trump supporters don’t actually know what’s in the constitution beyond the 2nd amendment

That is almost certainly true. Good point.

If he were to directly say, “I don’t care about the constitution,” a lot of his supporters would denounce that.

“Do you throw the Presidential Election Results of 2020 OUT and declare the RIGHTFUL WINNER, or do you have a NEW ELECTION? A Massive Fraud of this type and magnitude allows for the termination of all rules, regulations, and articles, even those found in the Constitution,” Trump wrote in a post on the social network Truth Social

IDK how many MAGAt's actually read Truth social, but that can't be any more clearly stated.

if he tries to denounce the conspiracy, he will be denounced. But only time will tell if they will, or if he even needs them now that he’s in power.

He has denounced it, and it doesn't seem like he's going to reverse that position. I hope you end up being right by the way. I'm admittedly a pessimist.
