If you just change from CSM/BIOS to UEFI then your computer will simply not boot. Windows does not support booting from GPT disks when in BIOS mode, meaning you must have an MBR disk, and it does not support booting from MBR disks when in UEFI mode, meaning you must have a GPT disk.
Is it okay to switch from legacy to UEFI?

What happens if I change boot mode to legacy?
The regular way of booting into software and operating systems is called “Legacy Boot” and must sometimes be explicitly enabled/allowed in the BIOS settings.
