So can I (as can anyone else). CSM is a compatibility module that allows legacy devices to boot in UEFI. Nothing new here.
If you mean separate settings in the BIOS/UEFI, that's certainly true of my Gigabyte boards as shown in post #30. And yes, it is possible some boards may have a single setting - say a "Secure Boot" setting that automatically disables CSM when enabled.
If you mean Secure Boot being enabled whether CSM is disabled or not, well in my experience as a system builder, and Microsoft saying the same, CSM must be disabled for Secure Boot... Windows 11 and Secure Boot...
To change these settings, you will need to switch the PC boot mode from one enabled as “Legacy” BIOS (also known as “CSM” Mode) to UEFI/BIOS (Unified Extensible Firmware Interface). In some cases, there are options to enable both UEFI and Legacy/CSM. If so, you will need to choose for UEFI to be the first or only option.
