Unregister senes from AIcontroller with perception component?

HI Guys

Well first time i had to post a question in there.

I find it impossible to unregister a sense from an aicontroller that has a perception component,
The “unregister sense” notes has no effect.when the controller has a perception component.
In my case i have an eye that need to see, but not be seen.

Hope the example makes sense.

Thanks for reading this.
