I read some blogs which says that the device uses the UEFI firmware called "AUTOPILOT_MARKER" to retrieve the Autopilot profile. To test this, I loaded my vm with windows 10 22H2 (19045.3693) and searched using powershell cmdlet (GET-UEFI) but I don't find any UEFI variable called "AUTOPILOT_MARKER". I even don't find it in registry. Can someone clarify this.
Note: I have not yet registered my device for Autopilot
