Splashscreen and AdControl in XAML

Hello. How can I do the Splashscreen cover the AdControl but when it close the AdControl appears again? And second part: should I even doing that? In Personal Edition of Unity the Splashscreen need to be showed, right? If I hide AdControl via C# code Splashscreen will be fully shown but technically AdControl will be covering it. Is that would be fine? Thank you.
