Mod to nullify Serrana dmg on other followers?

So i want to make Serana stop aggroing other followers, because everytime she throws the Ice wind at least one follower starts a fight between them. I have simple offence suppression and its addons to block friendly fire and It seems to work with everyone but her. Anyone know a fix for this?

I got Serana dialogue addon and edit, if that affects this, and dont manage her with AFT, other followers yes.

Maybe another follower manager with something similar?
