Here are the latest instructions from Amazon, as of August 2018: https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/nodejs-platform-proxy.html

(I have just used these instructions to customize the Nginx proxy for a Node.js app on Elastic Beanstalk, and it works as expected.)

Basically you use your own proxy.conf for Nginx, and remove the auto-generated stuff.

# .ebextensions/proxy.config
files:
  /etc/nginx/conf.d/proxy.conf:
    mode: "000644"
    owner: root
    group: root
    content: |
      upstream nodejs {
        server 127.0.0.1:5000;
        keepalive 256;
      }

      server {
        listen 8080;

        if ($time_iso8601 ~ "^(\d{4})-(\d{2})-(\d{2})T(\d{2})") {
            set $year $1;
            set $month $2;
            set $day $3;
            set $hour $4;
        }
        access_log /var/log/nginx/healthd/application.log.$year-$month-$day-$hour healthd;
        access_log  /var/log/nginx/access.log  main;

        location / {
            proxy_pass  http://nodejs;
            proxy_set_header   Connection "";
            proxy_http_version 1.1;
            proxy_set_header        Host            $host;
            proxy_set_header        X-Real-IP       $remote_addr;
            proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
        }

        gzip on;
        gzip_comp_level 4;
        gzip_types text/html text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript;

        location /static {
            alias /var/app/current/static;
        }

      }
