Exclude some URL paths to open the apps? (Deeplinking - Ionic2)

Question

I want to exclude some URL paths to prevent them open the apps because the content is not available for the Android app.

Below is my example URL and action:

http://www.example.com/ (open app)

http://www.example.com/path/to/content (open app)

http://www.example.com/pathto/content (open app)

http://www.example.com/pathtocontent (open app)

http://www.example.com/help (do not open app)

http://www.example.com/contactus (do not open app)

How can I do this? Is there any way?
