@Brett Vaughan, Thanks for posting in Q&A. Based on my researching, the camera roll can backup photos to Microsoft OneDrive. We can turn on "Camera backup is off" in OneDrive app.
From Intune side, based on my checking, I find there's no existing app configuration policy setting to set above feature.

Currently, we can only manually set it. You can feedback to OneDrive support to see if we can get this app configurator policy setting in the future.
