You can configure PiHole the same with DoH and DoT as well But not sure about the profile “.mobileconfig” for Apple devices AdGuard Home web interface generates it not sure how you would do that with PiHole. But you only need unbound if you want recursive dns that is what I am doing with AdGuard. As for DoH and DoT you can do i don’t remember what was involved I only set it up once and then switched to adguard home. Just preference mainly.
