Htaccess and Bitrix replacing _ with - in the page url?

Question

1C-Bitrix

There is the following code that changes the _ in the url to - But unfortunately this rule also applies to the admin panel. And as a result, the entire admin panel breaks because of this. How to make _ replaced by - only on the site? For example site.ru/primer_primer changed to site.ru/primer-primer Or is there another way?
