Remove /page/ from pagination urls

Hello,

I’ve searched all day about this but without a success. As you know when we use custom structure of permalinks – category, search and etc pagination URLs are like:
https://domain.com/category-name/page/2/
https://domain.com/search/phrase/page/3/

I want to remove /page/ from the url and leave only numbers:
https://domain.com/category-name/2/
https://domain.com/search/phrase/3/

Please help. Thanks in advance.

Regards,
R.
