Hi, I'm trying to enable secure boot in the BIOS in order to upgrade from Windows 10 to 11. Windows 10 is already in UEFI mode and the SSD in GPT mode, TPM is also enabled, but when I try to change "Secure boot" to enable it says that I must first disable CSM in Setup. The problem is that in the CSM setup page I only have 3 options. In the manual it says there must be four options and the fist one (the one is missing in my setup) is for disabling CSM. What do I do to show that option in order to disable CSM?
