Delta 3 BIOS USB Boot issue

Unable to boot for USB 3 or update BIOS.  Current version of BIOS is not the production launch version.  It is dated 03/24/2022 11:114:10

I've tried following the instructions for formatting 32bit fat.  copying 2 directories and single file on to the a USB flash and a USB SSD drive.  I've also tried installing the same files onto the UEFI SSD installed via M2 that shows up in the BIOS.  Non of the USB devices show up in the BIOS.  None of the 3 tried methods are useable for updating the BIOS.  Also uSD card doesn't work either.
