How do I lock the camera?

I'm making an infinite obby game, where blocks are teleported infront of the player as they are needed. To try make the game more controlled, I have locked the camera first person, but I want to to constantly point forwards(Along the X axis), however I can't find any ways to do this. Does anybody know method?

Look it up in the wiki

Or, on the top of the website, there is a search button.

Hope it helps!
