Start working and follow the guide, its a quite easy mod, you can share here your mod file for verification before the flash, perform backups of the current bios on system for safe keeping the motherboard original data.
The resulted mod can be then flashed with M-Flash utility in bios post.
EDIT: So go for it, users who performed the mod on their own Intel_image bios region, will not share it as it contains its own motherboard data, only the ones with a mod from the “Blank” MSI bios update file.
