Block Post comments link – edit

Hello, I would like to edit block Comments link, could you please help me?

Is it possible to translate word “comment/comments” to czech?
– ?ádny komentá? / 0 komentá??
– 1 komentá?
– 2 komentá?e, 3 komentá?e, 4 komentá?e
– 5 komentá?? …

Or is it possible to add option to make “comments” hidden/visible (or any other editing option)?

Thank you, Lucie
