AMD RX6800 black screen while installing SONOMA

Hello Everyone,
I just upgraded my GPU from RX580 to RX6800 after installing the new GPU it gave me the
black screen while booting to the OS, then I knew about the argument I should put to make it working
which is agdpmod=pikera and it worked, the geek bench score on the new GPU is not stable some sometimes give me, really high values and sometimes do not, I thought it would be better if I made a clean install and at the same time I upgrade from Ventura to Sonoma, the problem started here although I already use this argument I wasn't able to boot the installer it gives me a black screen again, So what should I do?

EFI::
CPU:i9-10850k
Ram:4*16 crucial ballistics
Mobo:Z490 Vigion G
GPU: XFX Speed Tester RX 6800
Wifi: Brodcom Wifi
Storage: 3*nvme /1 for win / 2 for macOS
