AWS elastic beanstalk redirect www to non-www with nginx location?

I'm trying to redirect www to non-www on elastic beanstalk, but I can't find any info on how to do that with nginx.

I have a location config that redirects http to https. Is there a way I can do this inside that config? I'd have to override the base nginx config to add a server config (which is the recommended way to do it according to the nginx docs), which I'd rather not do if I don't have to.

location / {
     set $redirect 0;
     if ($http_x_forwarded_proto != "https") {
       set $redirect 1;
     }
     if ($http_user_agent ~* "ELB-HealthChecker") {
       set $redirect 0;
     }
     if ($redirect = 1) {
       return 301 https://$host$request_uri;
     }

     proxy_pass          http://127.0.0.1:5000;
     proxy_http_version  1.1;

     proxy_set_header    Connection          $connection_upgrade;
     proxy_set_header    Upgrade             $http_upgrade;
     proxy_set_header    Host                $host;
     proxy_set_header    X-Real-IP           $remote_addr;
     proxy_set_header    X-Forwarded-For     $proxy_add_x_forwarded_for;
}

As I commented, I would use different server blocks. If you don't want, I would use the logic on $redirect as a boolean, and redirect hardcoding the $host, you want it without www anyway, don't you? Would this fit in what you want to do?:

location / {
     set $redirect 0;
     if ($http_x_forwarded_proto != "https") {
       set $redirect 1;
     }
     if ($host != "www.example.com") {
       set $redirect 1;
     }
     if ($http_user_agent ~* "ELB-HealthChecker") {
       set $redirect 0;
     }
     if ($redirect = 1) {
       return 301 https://example.com$request_uri;
     }

     proxy_pass          http://127.0.0.1:5000;
     proxy_http_version  1.1;

     proxy_set_header    Connection          $connection_upgrade;
     proxy_set_header    Upgrade             $http_upgrade;
     proxy_set_header    Host                $host;
     proxy_set_header    X-Real-IP           $remote_addr;
     proxy_set_header    X-Forwarded-For     $proxy_add_x_forwarded_for;
}

like this you end with only 1 redirect to the correct scheme://host . Or is there anything else you are configuring in this location block that I need to consider?

I hope I helped.
