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...
From Libreboot website:
"Libreboot already disables the Intel ME by default, using me_cleaner"
If you have a T480/T480s:
"Libreboot uses both me_cleaner and deguard on the T480/T480s."
