@Jbb08 : You did all the steps correctly. Can you please confirm if the external ventura SSD was created indeed from a non-mdm mac?
Is it possible for you to use the previous non-mdm mac and reboot from the external ventura ssd. Log into the admin account and run the same sudo profiles command to make sure you get "Error fetching Device Enrollment configuration: Client is not DEP enabled"?
I rechecked on the MDM enabled M1 Mac at my end and I am still getting the above correct message with sudo profiles show command. I also pigned iprofiles.apple.com, mdmenrollment.apple.com, deviceenrollment.apple.com, gdmf.apple.com and I was able to ping all the servers with DNS correctly providing their ip addresses back. Rechecked again with the command with the same correct response.
I am not sure what went wrong at your end but I strongly suspect the external ventura SSD you created. Both bootable usb ventura installer and external ventura installed ssd should be done with non-mdm/non-dep Mac.
At no point I had turned off the internet when I was restoring. Could you please redo all the steps without turning off internet?
