When we enable "Block write access to devices configured in another organization" in Intune Bitlocker policy. 
We also need to deploy an Onprem GPO "Provide unique identifier for your organization". This will allow the PC to differentiate the Org it belongs to.

"Provide unique identifier for your organization" is missing in Intune. Because of this we cannot use "Block write access to devices configured in another organization" policy.
Looking for suggestions how we implement "Block write access to devices configured in another organization" in Intune for Azure AD Join (not hybrid domain join)?
