    Can i safely change my BIOS from UEFI with CSM to UEFI only?


    Hello,I really want to turn on Secure Boot, but that is not possible if my BIOS is UEFI with CSM and not UEFI only. I have checked my drives2 and they are both GPT and not MBR. As for Secure Boot itself, in the BIOS it says it's enabled, but obviously it doesn't show up while in windows 11 and doesn't work since my BIOS isn't UEFI only. My question is: Is it safe for me to change the BIOS to UEFI only? Will i lose all files? Are there any features or something similar that will change with that? My operating system is windows 11, and I'm using an MSI laptop.I'm quite scared i'll lose everyth
