Switching to W11, but UEFI or CSM?

The fateful date is fast approaching, my question is how to switch to W11 knowing that I am currently in CSM startup and this is what is blocking this passage in Windows Update.
this mode has already bothered me a lot after each update of the bios (twice) of my CM. the PC no longer wants to start, it goes into uefi originally after update and even after putting csm back on it doesn't want to go away, and suddenly it wants to boot....

I have an MSI pro Z690-p ddr4 with a 12600KF, and a P3 nvme 1To SSD.
