Increasing worker_connections of nginx on Beanstalk nodejs environment

I am trying to increase the number of possible worker_connections of my nginx on my Beanstalk nodejs server (Amazon Linux 2).
I followed the documentation and created a file .platform/nginx/conf.d/proxy.config with this content:

worker_rlimit_nofile 65536;
events {
  worker_connections  32768;
}

When deploying I get the error: [emerg] "worker_rlimit_nofile" directive is not allowed here in /var/proxy/staging/nginx/conf.d/proxy.conf

When commenting this line I still get: emerg] "events" directive is not allowed here in /var/proxy/staging/nginx/conf.d/proxy.conf:3
