Stable url for product with attributes for SEO

[webprog]

Hello, how can I make stable URL of the product which have attributes in prestashop 1.7.

For example, now, I have product with attributes, and this product has different urls:

category/420-920-nurki-cena.html#/2-razmer-55
category/420-921-nurki-cena.html#/3-razmer-56
category/420-922-nurki-cena.html#/4-razmer-57

depending of the chosen attribute. I need, something like:
category/420-nurki-cena.html

or better for indexation.

Better have clean url like domena.pl/nazwaproduktu.html although it dont really have any impact for SEO. But looks better for clients, to share link on social media etc.

There are a lot simple url modules to use for it.
