How to disable hero kill experience?

[JFAMAP]

Hello everyone. I want to find out how to decrease hero kill experience
OR
Remove hero kill experience (so i can give it with triggers)

Is there a way to do that? We can increase, decrease or even remove experience gained from non-hero units easily but i want to change it for heroes.

Alternative solution is decreasing experience gain rate and increasing unit levels but it could be nice if we can make it only with heroes.

Update: I found it if anyone needs: Hero XP Gained - Hero from Gameplay Constants

You have these actions if you don't want to change constants

• Hero - Disable experience gain for (Triggering unit).

For all heroes of a player

• Hero - Make Player 1 (Red) Heroes gain 0.00% experience from future kills
