Hi, sorry if it's not in perfect language. I have an RX 6700XT, I'll list the two phases, everything is by default, sometimes it starts normally and most of the time, the motherboard LED remains lit to indicate the video card and black screen, I press the power button to turn it off , redoing and it starts. Phase 2: if I disable the CSM to activate the SAM, it gives me a black screen and always LED indicating the video card, after several turns off and on, the error screen appears "the GPU does not support the UEFY drivers" as in the attachment. Thank you.
