Help me please with my Asus tuf FX504GE

Hello, I’m trying to flash modded bios myself on Asus tuf fx504ge, but stuck on “error 167 protected…”
Maybe I did something wrong, could you please help me, I wanted to unlock all hidden menus to oc ram, since I have two 2666 modules with different timings and bios decided to run them on 2400, and play with CPU settings to reduce voltage, thank you a lot. This is dump link dump.rom - Google Drive
Edit: bypassed error and flashed modified by me bios but nothing changed, could you please make it right for me?
