Any mods on this modern bioses should be worked only in an Intel_image bios region, extracted with UEFI tool or Intel FPT tool (Yours is ME15 tools package), not working in an AMI Aptio capsule bios file. There are no leaked AMI tools to mod these modern files, options to try IFR extract tool/HEX edit variables/strings, AMISCE, RU tool, etc…
Flashing mod files are usually detected by bios internal security, can be bypassed by USB BFB method or Intel FPT tool if access to the bios region is allowed in the FD, this also can be unlocked on some motherboards. Last resource an SPI programmer.
You need to read a bit more on the forum… many similiar situtations, dont ask me more info, dont have time to spare with this, your task only or wait for other users opinion. Good luck.
