Question No Bootable drive found when CSM disabled.. Trying to enable Resizable Bar.

[Heronization]

Built a computer last year for the first time, and thought I'd try this Re-Sizable Bar feature for the RTX 3080. However I ran into a problem, Resizable Bar requires CSM to be disabled, and when I disable CSM my Samsung 970 Evo Plus 2tb M.2 Drive cannot be found in the BIOS at all, with nothing to select as a bootable drive. I've been searching google for an answer but I'll admit I'm super confused... Anyone know a solution? Thanks!

Specs:

CPU: Ryzen 5600x
MB: Asus B550i
Storage: Samsung 970 Evo Plus 2tb M.2 Nvme
Ram: T-Force 32gb 3600mhz
Graphics: RTX 3080
Case: NZXT H1
Windows 10 Home 64bit
