Monterey - Disable iCloud Desktop and Document Folder Sync
The macOS system's ability to automatically synchronize a user's desktop and documents folder to their iCloud Drive _MUST_ be disabled. Apple's iCloud service does not provide an organization with enough control over the storage and access of data and, therefore, automated file synchronization _MUST_ be controlled by an organization approved service.
This is implemented by a Configuration Profile. mobileconfig profile info: com.apple.applicationaccess: allowCloudDesktopAndDocuments: False
