Any progress on this David? We have looked through the documentation. There is no explanation for how to deploy Guides via Intune. The links you provided only mention how to update it via the store, which requires the user to manually check the store, or rely on whenever the store manages to update the application itself.
Your links provide information on how to update LOB apps via Intune on HoloLens. Guides is not a custom LOB application to my knowledge.
For guides specifically it says the following:
"How to update Dynamics 365 Guides (and other store apps)
Dynamics 365 Guides is an In-Box app, and can be updated through the Microsoft Store app. For all apps that are downloaded through the Microsoft Store, they can be updated through the Microsoft Store app itself manually."
Then it goes on to explain how to update custom Line of Business applications.
If we were to even try to manage Guides via Intune on the Hololens we would also need the link to Guides on the Windows Store for hololens and to do that we need a web link to Guides for HoloLens on the Windows Store. This link doesn't appear to be available, the only link we can find is the Guides Desktop Application. Guides for HoloLens appears to only show up when you are in the HoloLens and looking at the windows store. We cannot see a way to get a web link from the HoloLens store listings.
