Just made a Mac Ventura VM (Mac Guest on Windows Host) to test out Serial Numbers enrolled in MDM.
As per my testing, Ventura setup can be continued on a VM with Mac Serial number enrolled in DEP, provided internet is either filtered or disconnected.
If internet isn't disconnected then Remote Management Screen does come.
This was setup bypassed, and now after hosts file edit it can be bypassed again
