In the docs it looks like something allows you to set a background replacement image in the Control Center controls (like on a Mac).
However, I can't find any documentation on it, beyond this reference in the Apple docs. https://developer.apple.com/documentation/avfoundation/avcapturedevice/isbackgroundreplacementactive?language=objc
Does anyone have any advice to enable backgrounds in the camera system wide?
