How to disable indexing of sorted pages?

Question

Search Engine Optimization

On the catalog pages of the online store there is sorting by some parameters, it doesn’t matter.
A page without sorting has something like this URL:
site.ru/catalog/123
where, 123 is the category id, which, accordingly, can change. The
URL of the page with the selected sorting looks like this :
site.ru/catalog/123/sort1
there are several sorts, and at the end there can be sort2, sort3, etc.
