I'm not sure if it works on Finder, but you can use Pictogram and use icon files from macOS Icons to change the app icons. Source: about 1 year ago

If you don't want to change the icon manually everytime after an app update, you should get Pictogram. Source: about 1 year ago

Pictogram is free and does the job. It doesn't work with apps from the App Store, but neither do any of the alternatives so if you want to customize those you'll have to do it manually. Source: about 1 year ago

That will not persist across app updates. Pictogram can do this though (it's free). Source: over 1 year ago
