Is it possible to disable iMessage or FaceTime on an iOS or iPadOS device? My company is heavily regulated and since iMessage cannot be audited, we need to have this functionality disabled. In turn, is possible, we would like to disable the option to log into iCloud completely if possible. From what I've read and seen online, it is absolutely possible on MacOS but the mobile versions not so much...
Ideally if we can retain SMS and just disable the iMessage that would be for best.
