Looking for the latest AFUWIN that supports /GAN and doesnt cause Security Rom Fail issue. That would be super helpful.
check on Asus website the support page of your mainboard, usually in you can find the ME update only in BIOS tool sections. Apply it
You can get a newer version here: https://forums.mydigitallife.net/threads/bios-tools.529/page-70#post-1808886
This is not the fault of the tool incorrect operation - the BIOS on Gen 8 mobo is so done that it allows you to change some DMI values only once. Before changing DMI, UEFI WriteOnceStatus variable is 7F 7F ... and after a change DMI changes to 01 04 01 00 7F 7F ... To edit DMI again, just change the value back to 7F 7F ... https://forums.mydigitallife.net/threads/dmi-write-error-err_dmi_read_only.88282/#post-1834723
