az rest --uri not support some Graph Endpoints e.g. /deviceManagement/deviceShellScripts

Per our testing, az rest --uri not support some Graph Endpoints e.g. /deviceManagement/deviceShellScripts, since Azure CLI (1st party app) doesn't have the required delegated permissions.

However, our document doesn't mention that. May I know if any plan for letting az rest support that? Or can we update the document letting us know that limitation?
