@Joseph (Chilin) Wu / FPC Management Center Thank you for reaching out to us, this ask is not possible to add the machine/device group which is from Entra in NPS console - Conditions (tab) - Machine groups.
Groups conditions specify user or computer groups that you configure in Active Directory Domain Services (AD DS) not in Entra, more over the NPS server is part of on-premise network.
Any specific reason you have to add device group in the above mentioned section?
Let me know if you have any further questions, feel free to post back.
