Lenovo Legion 5 Tower AMD unlock hidden Features

it is a:

Legion T5-26AMR5 Desktop (Lenovo) - Type 90RC

i want to use XMP Profiles. I cant see them/active them in UEFI.

is it possible to enable this?

any ideas how to do this? i am totally new, but i cann follow guides etc… is there a chance to modify this? has anyone a hint for me?

It needs an SPI Programmer, as AMD . may be we can reflash the bios by AFUWin64 /GAN …
Try to make a bios backup and refwrite back by AFUwin64 and let me know if you get some error, or say me if there are others way to flash the bios on this system …
