Can I use RewriteRule (htaccess) in Cybepanel?

I started using Cyberpanel from this month.
No matter how hard I try to find out, there are things I can’t do, so I’m asking questions elsewhere, but the response isn’t good, so I’ll ask again here.
The RewriteRule below doesn’t work for the middle Rule only.
How do you get it to work?

RewriteCond %{REQUEST_FILENAME}\.php -f
RewriteRule ^(.*)$ $1.php
