How to enable the AllowOverride directive?

How to enable the AllowOverride directive? Can httpd.conf be accessed from the control panel?

If not, where is the location of httpd.conf after I SSH into the server?

System:
Debian 12.9
Hestia v1.9.2
Proxy Server: nginx
Web Server: apache2
PHP Interpreter: php-fpm

As far as I know, Allow Override is already enabled for all apache sites.
Its specified in the file /home/user/conf/web/domain.com/apache.ssl.conf
And it sets it for the directory
/home/user/web/domain.com/public_html
All dirs below that will inherit that setting.

If you want to turn it OFF, you can do so in the .htaccess file in that dir or any one below that.
