Unable to have ethernet or wifi on B550

Hi, I'm trying to install macOS Big Sur on my setup but the ethernet option in my network setting do not appear. I need some help please

I tried the LucyRTL8125 kext, I tried also without that kext.

Setup : Asus Rog Strix B550-F Gaming AMD Ryzen 7 3700x Gigabyte RX 5700XT

Big Sur installed just fine but ethernet option not appearing, If wi-fi or ethernet could word, juste one out of the two would be perfect but none work for me.

Thanks guys
