How to write 301 redirect in htaccess file from www to non-www for directories beyond the second one?

Question

Search Engine Optimization

Task
Make a 301 redirect for all pages of the site from addresses with www to addresses without www.
Now this solution works for the main and first-level sections:

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

For sections of the second level and below, when entering a url with www, it gives 404.
Question
What should be added to htaccess so that all pages of the site with www are redirected to pages without www, regardless of nesting?
