Want to permanently remove pagination number page/2/

I’m using GeneratePress (GP) theme. I am using this theme infinity scrolling feature instead of pagination.

But problem is when I go to homepage or category page and type /page/2/ (for example /page/2, it could be page 100) with domain name like domain.com/page/2/ or domain.com/category/bike/page/2/ still showing the result.
But I want to remove these page I mean when anybody type this /page/2/ they will see page not found notice.
How can I do that??
