Can a material/decal ignore post processing material?

Hi all :), please help ! I was wondering if is there a way to make a certain material or decal to ignore the post processing material from the post processing volume so it can render the actual color of that material/texture. Is it possible? is there a way to do this? to exclude just the material from being affected by the post processing? [I know that for meshes is possible but what about just materials?]
