No Boot to USB option Dell Optiplex 3080

No boot to USB option in a Dell OptiPlex 3080 with BIOS 1.3.2, nvme ssd

We are trying to boot to a usb which I created in Rufus and tried both GPT (non CSM) and MBR (CSM).  I tried changing all related options and disabled/reenable secureboot.  I also tried creating a Linux and WinPE bootable USB within backupper.

The only options are Windows Boot Manager, Lan1 and Lan2..  I know legacy boot is gone with this gen processor so that's not there.

I did read somewhere where if you wanted to boot to a CD/DVD, you need to manually add it, unfortunately I didn't see the "cd" option in the file system list.

I tried re-flashing 1.3.2 and defaulting the settings.  Any help is appreciated.

another used reported the following works in another ##8# Dell that has uefi class 3 (post sunset of legacy bios).

First and foremost prepare uefi bootable usb stick and plug it in pc before powering up, otherwise it would not show up in bios.
