Those settings that you see currently in the dashboard applies to the entire zone: doesn’t matter if it’s www.example.com, foo.example.com, bar.example.com, etc.

If you want to apply different settings for different types of traffic (such as disable Polish for foobar.example.com/nopolish), then you may create a Configuration Rule to override the global setting.

In fact, some quick Googling on “Cloudflare Configuration Rule” should return relevant results to you:
