Yes, sorry. There is no such setting for the Apple TV app on Windows.
You can neither access shared libraries nor share libraries from the Apple TV app on Windows currently.
Also, yes, when installing Apple TV, Apple Music or the Devices App, it disables the iTunes Application as these apps are meant to replace it.
You can offer Apple Feedback about it, and if enough people do, they may choose to add the feature to the App.

Currently, if you need to access Home Sharing, stay with the iTunes Application.
