对于某些网址，从 https 重定向到 Nginx 中的 http

Question

I have an Nginx configuration with ssl installed/enabled, and everything works fine, but I need to disable https on certain urls. I have tried to achieve this but I'm stuck at the redirect loop between https to http and back. Please see my configs in the image below, any help will be appreciated.

server {
   listen         80 default_server;
   listen    [::]:80 default_server;
   server_name    server_domain.com www.server_domain.com;
   root   /var/www/html/path_to_app_folder;
   index  index.php index.html index.htm;
   listen [::]:443 ssl ipv6only=on; # managed by Certbot
   listen 443 ssl; # managed by Certbot
   ssl_certificate /etc/letsencrypt/live/server_domain/fullchain.pem; # managed by Certbot
   ssl_certificate_key /etc/letsencrypt/live/server_domain/privkey.pem; # managed by Certbot
   include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
   ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot

   location ~ ^(/prime.*) {
    #default_type text/html;
    #return 200 http://$server_name$request_uri;
      return 301 http://$server_name$request_uri;
   }

}

Use $scheme

if ($scheme = https) {
    return 301 http://$server_name$request_uri;
}
