This is my nginx settings!

[NoorQureshi]

server {
    # Listen on port 80.
    listen 80;

    # Various standard security headers.
    add_header Referrer-Policy "no-referrer";
    add_header X-Content-Type-Options "nosniff";
    add_header X-Frame-Options "DENY";
    add_header X-XSS-Protection "1; mode=block";

    # CSP to only allow local content.
    add_header Content-Security-Policy "default-src 'self'; frame-ancestors 'none'; sandbox";

    location / {
        # Media location.
        root /home/example/media;

        # Turn on file indexing.
        autoindex on;
    }

    # Your local DNS resolver.
    resolver 192.168.0.100;
}

How can i implement this method here? Please help
