How to change a selection effect in editor

I'm working on some editor tool and I'm currently trying to make a feature that allows to mark some GameObjects in the scene view with a custom effect, so they become more noticeable. The problem is that default selection effect of Unity (that highlights an object when we click on them) disrupts the final view of selected GameObject. I wish I could disable that default effect for the time I place my own selection effect, and return it when I done. Is there any way to do that?
