Microsoft Purview Data Loss Prevention will soon support adding SharePoint sites to administrative units. Public Preview starts late April 2025, and General Availability begins mid-June 2025. Admins can configure this by default, but only the All-sites option will be supported. No admin action is required before the rollout.
