No, Trump did not call for termination of the Constitution, not in part nor in whole. The entire commentary is clearly preceded by a conditional introduction
Oh really... Let's take a closer look at that to see if it holds up under any level of rational scrutiny. Here is the entire truth social post:
So, with the revelation of MASSIVE & WIDESPREAD FRAUD & DECEPTION in working closely with Big Tech Companies, the DNC, & the Democrat Party, 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. Our great “Founders” did not want, and would not condone, False & Fraudulent Elections!

First thing to note is that this is not even a conditional statement, as in if X then throw out the constitution. He's already asserting X so he is in fact unequivocally calling for the constitution to be set to the side. That's your supposed red line with Obama, but somehow doesn't apply to Trump. Shocking.
Second, the election wasn't stolen. So at best, you can argue the man is totally delusional. Kind of odd that you are still attacking Obama while we have a delusional Commander in Cheif.
Third, this is Trump's tired old game and he does this with everything. You act like it's some kind of grammatical genius, but this is really simple; Trump has figured out that if you can just lie, you can make an excuse to take any action you want. It's really simple; "I want to do B. If A then B. [Lie about] A, therefore B". It's exactly what he's done with the DOJ, lie about democrats weaponizing it so he can excuse himself weaponizing it, and he's trying to do exactly that here.
The man doesn't care about the constitution or democracy and he never has, that's been made plainly obvious.
