@PhilienTaylor I’m not sure what your question is here. Your end goal is not clear based on what you have posted.
FOG doesn’t support imaging over Torrent. FOG doesn’t support Secure boot. There is a tutorial on how you can create your own keys and then sign the boot files. This will require you to upload the certificates into each hardware. Or to go to microsoft and go through the process to get microsoft signed signing keys for what you want to boot on the target hardware. FOG doesn’t have any utlity for hypervisor environments. The FOG server can run as a vm client, but FOG has no relationship with virtualization.
