Updates are possible via Windows, but some systems need this feature—especially older models like the X79-era EVGA boards. It’s usually not advised and tends to cause issues. The BIOS flashback process works better in practice, though it’s less common.
Check the details for your motherboard carefully. Some boards accept it, others reject it. It doesn’t seem to be a chipset issue but rather a hardware-specific one. For example, A320-MS2H from Gigabyte appears to support a tool called @BIOS, which is Gigabyte’s method to upgrade the BIOS from within Windows. I strongly suggest using that utility instead of just running an unknown program.
This capability isn’t always available on every modern motherboard, though I’ve encountered it in server environments and some premium enthusiast boards known as the EFI Shell. The EFI Shell can be understood as a command-line interface for your UEFI BIOS or possibly a separate utility integrated within it. You might have noticed it before: sometimes the board supports it directly, other times you need to install it via USB and boot from it. From this point, you can carry out low-level tasks such as updating the system BIOS without entering the UEFI BIOS itself. It may not match your expectations, but it offers an alternative path beyond using Windows or the standard UEFI BIOS Flash method on most boards.
I refreshed the UEFI setup and confirmed the board remains intact.
