Disable an Effect with Post Processing V2?

Unity Engine
1

I downloaded the post processing stack v2. I cannot for the life of me figure out how to disable a single effect on the post processing volume that I created (by script). Here’s what I’m looking for:

if (player presses a button)
{
ColorGrading.enabled = false;
}

or something similar. I got it to work with the last stack but I can’t figure it out with this one.
