Hello @Parm Dhesi ,
After looking at the additional settings for those disks (i.e. disk with SSE with PMK & ADE vs SSE with PMK) , the only different which I observed was :
for PMK with ADE - in the properties of the disk you will see diskEncryptionKey attribute
for PMK with SSE - in the properties of the disk there won't be key
Having said that , I was thinking of below modified queries to find out those types of disks
resources | where type == "microsoft.compute/disks"
| extend properties=parse_json(properties)
| where properties.encryption["type"] == "EncryptionAtRestWithPlatformKey"
| where properties.encryptionSettingsCollection["enabled"] == "true"
| project name, properties
Kindly let me know if you have additional questions !
regards,
Shiva.
