Use Intel FPT tool from the correct ME FW version to your motherbaord and make a full spi dump and
a bios_region only dump. Preserve the dumps for recovering bios if necessary.
Mod the bios_region with AMIBCP tool and flash the the bios_region mod again with fpt tool.
The menus not visible must be set to USER instead of Default in the correspondent parent menu.
Do NOT change individual strings and do NOT change the Failsafe/Optimal values.
Forum box search, Youtube and Google are your friends, dig it.
Or wait for another user.

Another option for flashing is swapping the bios_region mod, in a CAP file to use the in-bios EZ Flash.
Any straight mod flash will result in failing due to Asus security in bios
