Yes, if you want to dual boot with windows 11 you will need UEFI enabled secure boot is not needed as of now.
I think Windows 11 can be booted using legacy mode, I'm not sure how long they will support that.

From what I've been reading lately, most dual-boots may need UEFI enabled on the BIOS. That's what I need to look into in order to get my USB/portable drive to dual-boot.

Sadly, I've been having server issues...again.  And, I've busy with that and my grand kids. LOL

UEFI itself isn't a problem - the Secure Boot feature of UEFI is. Apparently it can be enabled in Linux but it's a pain to do so (see https://wiki.archlinux.org/title/Unified_Extensible_Firmware_Interface/Secure_Boot for more info). It's easier to just disable it.
