What can be configured via MobileConfig XML profiles? Apple's site is a bit technical, but from what I understand, MobileConfig XML profiles can be used for login credentials, WiFi credentials, and even 802.1X RADIUS authentication credentials. It can also be used to configure DNS-over-HTTPS/TLS, which is easy with online configurators, but those are limited to DNS-over-HTTPS/TLS profiles. Is there no other way to assemble a MobileConfig XML file without Apple Configurator? I own only one Apple device - Apple TV 4K, but I want it secured through 802.1X (EAP-TLS certificate authentication) and it looks like it cannot be done via Windows PC... Does Apple allow people to rent their devices for short periods of time? Can official retail Apple outlets help me generate MobileConfig XML files?
