anonymous user Thanks for posting in our Q&A.
For this issue, I have done some research. I find that Windows Pro Education builds on Windows 10 Pro in the following article. So, “ApplicationManagement/RequirePrivateStoreOnly” is not supported in Windows Pro Education devices.
From Intune's point of view, currently, there is no way to make it. During my research, I also find other customer who has the same requested posted in Intune uservoice as below. We can vote and post our detailed request here. This is a place to collect customers' requirements and problems.
Thanks for understanding and have a nice day.
