OnDisable() for Post Processing Stack effects?

Hello, I have done some custom post Processing Stack V2 effect.
The problem is in this effect I’m using a pretty heavy 3D Texture. And I want to get rid of it when the effect is disabled.
The ordinary OnDisable(): OnEnable(); not working for PPSv2 script. So what I can do?

I saw it has only
public override void Release() function, but this not happens when I disabling the effect.

The simplest thing would be to move that logic in to whatever script you are using to enable/disable the effect. (or are you talking about enabling/disabling in the editor?)
