[HELP] ASUS RX550 2GB GOP remove

Just installed new motherboard in my system on a AM3+ socket(GIGABYTE-GA-78LMT-USB3) and my RX550 just dont working on it. My motherboard is only in Legacy mode, and RX550 requires a UEFI.<br />Checking through the forum gave me some info about GOP and UEFI, but im not ready for modding BIOS by myself, i`m too scared to brick it because of my stupidity.
Can someone help me remove all that UEFI stuff?

Giving my original vbios and waiting for any response
