How to boot exernal USB (Linux)

I am trying to boot from an external USB and I am not seeing it as a boot option. I have gone over BIOS and I don’t see anything obvious to enable it. The drive boots in other PCs and I can the FAT partition fine when I boot into Windows 11 so the USB and drive is good.

What am I missing?

Upload the picture with the main BIOS window that contain all the main tabs.
