F17 (2022) - Can't find where to disable CSM

New owner of a F17 2022. I HATE Windows 11 (which came preinstalled) and am trying to rollback to W10. Made the USB using the official MS tool, but it won't detect my Intel NVMe drive, nor the brand spanking new Samsung I put in 5 minutes before.

Read online that I should try and get the NVMe driver and load it from the W10 installer, which I did but it still won't find the drives.

Also read that I should try disabling CSM but I can't find where that sucker is. Anybody has an idea where its hidden or what kind of obscure name Asus might have given it? The BIOS has the least amount of options I've ever seen on any BIOS, including specialized commercial and industrial hardware (yes, I went into 'Advanced' mode).
