OS
Windows 11 Pro 23H2
MSI Pro Z790-A Wifi motherboard
MSI RTX3060 Ventus 2x 12GB graphics card
Intel Core-i7 13700K processor (with integrated graphics)

Recently doing an experiment where I wanted to enable CSM mode on this motherboard.
When trying to change the BIOS setting it would not stick, throwing up a message:
"Onboard graphics V-BIOS is not supported in CSM Mode. The "BIOS CSM/UEFI Mode" will be changed to UEFI.

Problem is that this system does have a discreet graphics card and the BIOS setting Graphics Configuration > Primary Display Adapter is set to PEG (not IGD).
The Ventus card is V-BIOS compliant.

Any ideas of what the problem is here?
