I just happened to come across this note which led me to look into the libreboot FAQ that says the SPI flasher CH341A unmodified can damage the chip that's mentioned in the docs of the github I posted in my previous note. I'm trying to determine if the article's claims of removing ME/PSP are accurate if using libreboot. I think it might be bypassing it rather than removing or disabling it which can only be done though a flash or physical modification.
