How to remove .php and / at the end of pages and sections in Bitrix?

Question

1C-Bitrix

Hello!
I am transferring the site to cms Bitrix. Previously, our links to internal pages looked like this:
domen.ru/category/page

Now, when creating new pages, it all looks like this:
domen.ru/category/page.php
or (if we create sections instead of pages):
domen .ru/category/page/

i.e. .php and / slash are added at the end.

From the point of view of search engines, these are different pages. Our search engines have already optimized the site and now, when transferring, even while maintaining the entire structure, our SEO positions can suffer greatly due to these endings.

Is it possible to do something so that a slash is not added at the end of sections? and no .php was added at the end of the pages?
thank!
