That’s an interesting question, isn’t it? Even more, how AMT was enabled in the first place, if the UEFI has no option for it.

And I’ve had massive issues with AMT before – for some reason, on Linux, the ME would force a reset of the network connection every 90 seconds (which is why I use an ancient realtek network card currently).

Possible explanations include bad defaults in the UEFI, a store sending me a used part instead of a new part, etc. If we go into conspiracy territory, NSA TAO interception would also be on the table. Very unlikely, though.
