Can you disable Shared ally LOS via triggers?

[Serchant92]

Im trying to create a scenario with an ally AI which does not share his LOS.
I did it first with setting the diplomacy Ally towards the AI and Neutral towards mem but then I cant pass my units through his gates,
Switching the diplomacy didnt change anything, Also tried diabling LOS withthe PLayer: Set Visibility effect but that didnt work either,

Any help on this?

Yea I figured out what the problem was… There was another player who was allied to me too and forgot to disable their shared LOS.

Thanks anyway!
