There used to be the claim that "if you overclock your CPU/GPU, it would blow a fuse and the manufacturer could deny a RMA". Not sure if it ever actually happened, or if it was just an urban legend.

I could see a system management controller that blew fuses to track known potentially hazardous situations-- "Internal temperature while operating exceeded NNN degrees for XXX seconds" or "power surge in excess of NNN volts registered on this rail." Maybe a case for "paired part replaced" but that's more informational than accusatory-- a legitimate repair or upgrade could be an increase on any "health metric" they want to show.

But you'd want it someplace like, as I said, fuses on a SMC, maybe viewable in the setup screen, rather than a SSD which is not only easy to swap, but has legitimate reasons to do so (plenty of refurbishers install new SSDs because they're a cheap boost, or because they're sourcing from companies who have a "destroy the old drive on retirement" policy.
