How to make a unit not collide with player 9 units

How to make a player 10 ground unit not collide with ground units of player 9, but do collide with ground units of players 1-8? I still need a system where units 'Attack-Move to' a place but go for their objective when they can move through. I thought of a way of doing this, is to make a unit 'check' for whether theres a 'hole' that can be went through or not. For this I need this checker unit not to collide with units of player 9.

"Pathing - Collision size"
Set all player 9's units to 0, so no unit will collide with them, (including player 10's) but still collide with the rest of they palyer's units.

That technically works but it makes player 9s units able to go through the smallest holes so Im afraid I cant use this solution.

With triggers:
Custom script: set bj_wantDestroyGroup = true
Pick every unit in (Units owned by Player 9) and do (Actions):
Actions -> Set (Picked unit) collision size to 0.

A simple way to do it would be to run a periodic event that checks if any of player 10's units are in range of any of player 9's units. If it returns true, set the unit's collision to 0 - if it returns false, set it above 0. That way it will always have a collision size unless there's a unit owned by player 9 in range. Make sure you clean up leaks because such a large periodic event will lag extensively if there are any.

Set unit movement type to flying.
