How to make a postprocessvolume to affect the whole scene but one object?

For example, I set Chromatic Aberration Intensity for 10, can I exclude a objects from Post Processing and keep it from this effect.

The method I see is to use Custom Depth Stencils to make the object not affected by post-processing materials, so I want to know how to make objects not affected by the basic settings of post-processing?

Notice this post, where someone is using a sphere mask to exclude many areas from PP:

Also, using this technique:

It’s possible to isolate one area. In this case, they are only applying the PP locally, but it could easily be reversed.

Having said all this, it won’t apply to a basic PP setting. The easiest way to do that is to imitate the PP material and use your own PP volume. I assume it’s not possible to tinker with the basic PP settings unless you’re using C++.
