301 redirect from index.php

I just realized that the problem must be related to my htaccess. It has a configuration for index.php there. The problem is that this is generating duplicate content, as it is possible to access my site both with the final index.php and without it.

help me solve this

My .htaccess

<IfModule mod_rewrite.c>
    <IfModule mod_negotiation.c>
        Options -MultiViews
    </IfModule>

    RewriteEngine On

    # redirect http://www.example.com to https://www.example.com
    RewriteCond %{HTTPS} off
    RewriteCond %{HTTP_HOST} ^www\. [NC]
    RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

    # redirect http(s)://example.com to https://www.example.com
    RewriteCond %{HTTP_HOST} !^www\. [NC]
    RewriteRule ^ https://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

    # Redirect Trailing Slashes If Not A Folder...
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)/$ / [L,R=301]

    # Handle Front Controller...
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule ^ index.php [L]

    # Handle Authorization Header
    RewriteCond %{HTTP:Authorization} .
    RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]

</IfModule>
