AFM failures
I read about these failing for those that track their cars and thought it was mainly autocross.
At the last VIR full event with temps in the mid 90's I threw P12F0 & P12FD codes.
Will GM replace these if you have LT's & x-pipe installed?
Will removing fuse 32 eliminate the CEL?
Thanks!

If the AFM actuators failed the CEL will come on every time you start the car, even if you clear them. The car goes through a "boot cycle" each time it is turned on and checks all the sensors, I know this because I've experienced it first hand.
The dealer SHOULD cover it under warranty because it is a known issue to happen to 100% stock cars. Even Tadge somewhat acknowledged the issue in the fact that '17+ manual Z51's and GS's will no longer have AFM actuators. However it is possible the dealer won't cover it since the exhaust has been modified. FYI those actuators cost over $800.

Anyway, the only real solution is to remove it from the exhaust stream, so it doesn't overheat:
