MMTool Aptio 4.50.0023 is a specialized firmware management utility developed by American Megatrends Inc. (AMI) for modifying and managing
Certain security products flag MMTool.exe as “hacktool” because it is frequently used to modify firmware outside manufacturer control. This is a generic detection, not malware.
Use Mmtool to modify modules, then test the modified firmware in a controlled environment. It's crucial to verify that changes do not adversely affect device performance or stability.
Select the volume (typically the one containing other DXE drivers) and click . --- Mmtool Aptio 4.50.0023

What (NVMe boot, microcode, etc.) are you attempting to add? (AMI) for modifying and managing Certain security products
The most popular use case for MMTool 4.50.0023 is adding Native Non-Volatile Memory Express (NVMe) support to Intel Z77, Z87, or X79 motherboards. These boards were manufactured before NVMe solid-state drives became an industry standard. While they possess PCIe slots capable of hosting an NVMe drive via an adapter, their stock BIOS cannot recognize the drive as a bootable device.
Systems from 2018 onward (Intel 300-series and newer, AMD Ryzen 3000 series and newer) often enforce Secure Boot + Intel Boot Guard. A modified BIOS will fail the signature check, and the system will not boot—even from a backup BIOS. For these platforms, Mmtool 4.50.0023 is often . You must use the vendor’s own signing tools (or accept an SPI programmer recovery).
