finder – How can I change the icons of Mac System Applications ? like music, books, disk utility

I am trying to change Mac system app icons. I can’t just copy and paste the icon in the Info panel in Finder like I would do for an app from the App Store.
I have tried to change the user permissions down in the Info panel but this doesn’t work. I also have tried by disabling the SIP and it didn’t work either.
Does somebody know another way of changing icons of system protected apps?
