Could Intel ME be disabled in UEFI firmware setup (if the firmware were to offer a UI for it?) Or it is something that's physically enabled/disabled on the CPU

Could Intel ME be disabled in UEFI firmware setup (if the firmware were to offer a UI for it?) Or it is something that's physically enabled/disabled on the CPU and totally orthogonal to UEFI firmware? Ergo, could the computer manufacturer release a firmware update providing such an interface option in firmware setup if they really wanted to? Or are they stuck once the product is released?

You can disable ME by giving it a firmware image to run that does nothing. The me_cleaner approach is to keep the module that brings up the hardware and then give it a command causing it to crash, which is as good as that. A firmware update can definitely do this too.
