I have a B450M Pro4-f motherboard.
I want to disable (if possible) Amd psp from bios.
Is possible to did it? If not maybe in the future it will possible to disable this feature?

i really doubt that
this is the first thing that gets initialised with CPU registers, that security processor then kickstarts your normal x86 cores and after that UEFI firmware gets executed
its a cpu, probably arm based, with some mini operating system on it, without it, your CPU wouldnt even work as cpu registers, memory operations and mainboard firmware are routed through it
so no, you cant disable PSP
the only way to get rid of it is to downgrade your cpu

I have already ordered the only amd motherboard compatible with latest coreboot and most important thing, has fm2 socket which support the latest amd cpu family without psp.
