Some background: I work for a K12 district, and I had (mostly) successfully gotten FOG to work for image capture and deployment. The only hitch - discovered at the end of the process - was that FOG required SecureBoot to be disabled (and remain disabled) on the Dell Optiplex machines I"m needing to image.
Here's my scenario: I have a Linux host running VirtualBox, with a couple of different Win11 deployment images as virtual machines.
I have a Theopenem server which appears to be happily running in VMware (on a Windows 2022 server). The final config check returned a "60".
I've created a "placeholder" image on the Theopenem server for capturing the first image.
I've got the scope options configured on our Windows DHCP server. I can ping the DHCP server from the Linux VM host machine.
I have Toec installed on the Win11 VM image(s), and I'm running the Toec ImagePrep (invoking Sysprep and an XML answer file) as the last step before trying to capture. After the post-Sysprep shutdown the of VM, I'm going in to the settings for the VM, enabling network boot, and moving it to the first boot priority.
I've discovered that I have to disable UEFI in the settings for the VM in order to PXE boot the VM, but it's not seeing what it needs to from the Theopenem server (see attached screen grab).

Is there some element or factor that I'm failing to take into account?
Thanks for any tips...
