Wordpress - How to remove the slash from the end of %{QUERY_STRING}?

Question

Apache HTTP Server

Hello, there is some strange behavior of wordpress observed.
Native htaccess from wordpress and if I enter the address without a slash at the end - it is automatically added.
Everything would be fine, let it be added to itself, if it were not added after index.html
Has anyone come across?
It’s clear that this could be some smart-assed SEO plugin, but I deleted my .htaccess, cleared the caches, went incognito, and put the htaccess native and still adds it. Where can this be configured/disabled?

Answer 1

In the admin panel "Settings > Permalinks" what is it worth?

Answer 2

Has anyone come across?

Do you need a full list or will ten people be enough? With addresses and phone numbers?
Create a real index.html file then the VI will have nothing to do with it.
