@Darren Ramos Apologies for the delayed response, regarding your ask on how to manage stale devices in Entra id (not in intune) based on device location.
Thoroughly checked the Entra ID/devices section, I don't see any filter/attribute in Entra ID which captures the device location for devices.
You can refer to this https://learn.microsoft.com/en-us/entra/identity/devices/manage-stale-devices which has the detailed steps on how to manage stale devices in Microsoft Entra ID.
Let me know if you have any further questions, feel free to post back.
