Lan MAC Address got wiped

bahamida

Hi folks,

I bought a new mb GIGABYTE B650M AORUS ELITE AX ICE, placed cpu ryzen 7 7700 and gpu gtx 1060, no display when placed in gpu hdmi slot (sometimes there is) unless it is placed in mb one, so i upgrade the bios and did clear cmos and now lan mac address got wiped, it displays in bios (Lan MAC Address N/A) and ethernt slot not working anymore, could it be fixed if i installed a flushed bios with the mac address that i got from the motherboard ? (i dont know if that is even possible).

please help
