Post Processing v2 - Global settings for enable disable

In my game, I have an options panel where the player can choose what post-process wants to enable and at what level of quality.

I implement with post processing v1 modifying directly the code of the package.

I'm now porting the game to 2019 and I'm moving to post-processing v2.

How I can achieve that? The documentation (https://docs.unity3d.com/Packages/com.unity.postprocessing@2.3/manual/index.html) don't talk at all of this very common need for PC game.

The documentation suggests to do what I do the last time: "You'll find more methods by browsing the /PostProcessing/Runtime/PostProcessProfile.cs source file."

 

Finally I understand how to do that. The best way is to use QuickVolume:
