If you have inserted USB to machine when booting up, it should be able to see USB option on boot menu.

Have you format USB into bootable device? if yes, then it should able to be seen in boot menu.
Maybe we can try something:
1. Check "BIOS" → "Boot Manager"→ "Exclude Boot Device", if there is any device in here, please clear it.
2. Go to "BIOS"→ "Save & Exit"→ "Load Optimized Defaults" to reset BIOS, then try again.

I upgraded the BIOS of my TD350 from V3.34 to V4.25 just now and I still can see my bootable USB key with redhat OS both in boot menu and in BIOS boot manager. Here is the BIOS picture for your reference. The BIOS picture in my last post is without USB bootable key inserted and the following picture is with my bootable USB key inserted to my machine. And you can see the ''boot option #7 " which is my bootable USB key with redhat OS in the BIOS boot manager.
