I’m not sure what you are referring to without context but I can guess.
If you click the “eye” symbol next to whatever content you DON’T want to display. Then it won’t show when you load the scene. However in order to see anything you must have an action that changes the style display property to something other than “none” when you want to see the content.
Another approach is to move the content out of the viewing area and bring it in when you want to see it.
I can’t really help much more unless I see what it is you’re trying to achieve.
