You can boot usb from UEFI. The only tool that I found is best to handle is Rufus. I used it to clean install my Windows through UEFI. Even Linux Live USB works. BalenaEtcher gives me problems, Rufus does it well for me.

Also I remember there is a setting in UEFI to allow booting from USB.

It's possible, I've done it, it just involved a lot more steps. Simpler when I can `fdisk && mkfs && debootstrap` to make a key. Plus then I need to keep two bootable usb keys, I think... it's just... "Who ordered this??"
