How to remove PAGEN from pagination in the Bitrix product catalog?

Question

How to remove PAGEN_1 from pagination in the Bitrix product catalog? Perhaps someone has already implemented this?
There is a site on Bitrix with a standard catalog of goods. Seoshniki demand to change the CNC pagination in the sections of the product catalog! Now in the catalog section there is such a picture stoshin62.ru/catalog/legkogruzovye/?PAGEN_1=3 where PAGEN_1=3 - where 3 is the 3rd sheet of the list of goods in the section Light truck tires The link template is stoshin62.ru/catalog<section>/?PAGEN_1 =3
SEOs want it to be like this stoshin62.ru/catalog<section>/3 Where 3 is the third page in pagination and should not be specified by the PAGEN_1 variable in the browser line.
How can this be implemented? Set a new pattern for processing addresses in the urlrewrite.php file? Tried on blog.d-it.ru/dev/84 but didn't work.

Answer 1

I won't stop repeating

Seoshniki put forward such game as requirements for one reason, then to justify their poor results. They know perfectly well that this will affect the result by a little more than zero percent. But when they come to sign the act of closing the work and when asked why there is no result, the first thing they will say is: "Your IT specialists did not fulfill our requirements."

Answer 2

How can this be implemented?

So:
What hinders something? How did you try? I hope you changed the pagination template itself accordingly, under the rule in urlrewrite?
What they tried from Anton's blog is not clear. Moreover, it is not clear what did not work.
Yes - there is another option - to find competent SEOs.
ps if you find such, send a contact in a personal - I have not met.
