Can't Find USB boot on Supermicro MBD-H12SSL-I-B

Hey everyone, I seem to have been unable to locate where the USB boot choice is in my bios for the motherboard.

Currently it is setup with proxmox and boots fine but I wanted to try unraid and since it runs off a USB I thought I could just boot to the USB and try it out. So far however I can’t seem to get it to boot to USB (or maybe it’s not seeing the usb stick) Eitherway if someone knows how or if I am doing something that won’t work let me know.

I mostly wanted to check out unraid since proxmox and truenas seem a bit much for a home user with 2 vm’s running.
