Trying to use H5AI webserver indexer on my gitlab pages but requires an edit to my pages .htaccess or Apache's httpd.conf

Hello, I am trying to use H5AI webserver indexer to make my gitlab pages maven look nicer so I can make it public but I know that GitLab is running NGinx and that the .htaccess file in my gitlab pages site that would make H5AI work is useless. To make H5AI work, I need to put this line into the Apache config or an .htaccess file on my site DirectoryIndex index.html index.php /_h5ai/public/index.php Or this into the NGinx config index index.html index.php /_h5ai/public/index.php But, GitLab does not use Apache and uses NGinx, and since NGinx does not have a .htaccess alternative, the only way is to edit NGinx's config but that will never happen I was just wondering if there is a way to make this webserver indexer work on my gitlab pages

Here is the webserver indexer https://larsjung.de/h5ai/ Thanks, hope You can help
