How to make single 301 redirect with htaccess?

Question

htaccess

To redirect from www and http to https, I use the following code in .htaccess:

<IfModule mod_rewrite.c>
RewriteEngine on
RewriteBase /
RewriteCond %{HTTP_HOST} ^www.site\.ru$ [NC]
RewriteRule ^(.*)$ https://site.ru/$1 [R=301,L]
</IfModule>

There was a need to add a redirect to the file from all pages to the main one. This solution worked:

RewriteCond %{REQUEST_URI} !"^/$"
RewriteRule (.+) https://%{HTTP_HOST}/ [R=301,L]

But if you add it to .htaccess, then redirects from all pages from www to the main one are double. That is, it https://www.site.ru/fghdgsdfleads to https://site.ru/fghdgsdf,and only then to https://site.ru/.
