Disable Virtualization on Gigabyte Motherboard

I can’t believe Gigabyte doesn’t let you disable virtualization in the BIOS for some Intel motherboards. Many Reddit posts ask about this, and I found an easy way to do it that isn’t widely discussed.

This is the easiest way to do it. It is also quite safe. If something goes wrong, you can just clear the cmos and everything’s back to normal.

Note

This guide is only for MSI H410M H3 (rev. 1.0). For other motherboards, see here.

This was tested on Gigabyte H410M H V3 (rev. 1.0)
BIOS version: F9 (Dec 20, 2023)

Preparation

• modGRUBShell.efi
• A USB stick

Here’s the way I do it:

1. Format the USB stick to FAT32
2. Download the file modGRUBShell.efi and rename it to BOOTX64.EFI. Then put it on the USB stick so it looks like this X:\EFI\BOOT\BOOTX64.EFI. (X: is the USB drive letter)
3. Disable Secure Boot and then enable CSM in the BIOS.
4. Press F12 to boot the EFI shell from the USB stick. Select the one with UEFI: at the beginning.

5. In EFI shell mode, type this command:

   To disable virtualization:

   setup_var_cv CpuSetup 0xB9 0x1 0x0
   

   To enable virtualization:

   setup_var_cv CpuSetup 0xB9 0x1 0x1
   

6. Type reboot when you’re done/

7. Now its virtualization is disabled:

   

Where do I get these commands from?
