Block videos on Apple TV main screen?

Hi there!

I am a technology assistant at a public school system. Many of our teachers use Apple TV in their classrooms. We have a concern with the Apple TV main screen. Is there a way that we can hide the videos that pop up when you initialize the Apple TV? Many of the movies are inappropriate for young children and we were hoping there would be a way to prevent them from appearing every time we start up the Apple TVs. Just wondering if this was possible.

Thanks!
