@Kenneth Clausen - nyit.dk, James,Thanks for posting in Q&A.
From your description, I know that you want to maintain a specific version of a Microsoft Store app via Intune and prevent it from updating.
Based on my researching, I find that if you deploy apps from the Microsoft Store via Intune, they will automatically keep up to date to the latest version of the app. and if you enable Turn off Automatic Download and Install of updates, the UWP app will not update automatically and keep the specific version.
Moreover, you can deploy it as Win32 app or LOB app to maintain a specific version of a Microsoft Store app, they will keep the specific version that you have uploaded and deployed, and they will not automatically update unless you upload an update package.
