Accesing post processing setting via script

I want to change many different post processing setting for my game for supression,Aiming etc but I couldn’t find the way to do it smoothly for anything in post processing how can I achive smooth transition in post porcessing setting with script I can use any post processing version where it is possible

I haven’t tried doing smooth transitions, but the first thing I would try is experimenting with multiple post processing volumes and adjusting the weight, priority, and blend distance settings.
