How do I parallax part of layer?

Trying to make a multiplayer similar to Multiplayer tutorial 4: real-time game i have a problem with touchpad on screen.

The problem is if one of the player goes under the touchpad of the other player.

The host screen is this:

the peers screen is this:

Is there any chance to lock a 10% of left of the screen so i can put there the touchpad the score etc?

like this:

so the first 50 pixels on the right of the layout not move.

Note that i use scroll behavior.

Use a separate layer with parallax 0.

Or use the anchor behaviour.
