Modifying a BIOS carries a risk of "bricking" your motherboard. Always ensure you have a BIOS recovery method (like a USB flash drive with the original BIOS file) or a hardware programmer (CH341A) before proceeding.
While MMTool itself is a Windows-only executable, the process of adding modules (like NVMe support) can be followed on Linux or macOS. You would need to use alternative tools, such as UEFITool, to manipulate the BIOS image. However, using Windows is strongly recommended for the easiest experience, as MMTool and IFRExtractor GUI are exclusively designed for it.
