What configuration management system should I choose to change nginx configs?

Question

Chef

Hello gentlemen DevOps,
Unfortunately, I approach the implementation of the task after the fact and have a superficial understanding of configuration management systems. Since I used shell scripts before, I looked askance towards control systems and that was enough, until now).
What would you advise a beginner to solve the following problem:
Everything is pretty banal.
It is necessary to replace the nginx config on three proxy servers with the change of the current ip (proxy server) in the server block, /etc/nginx/nginx.conf
file :

server {
listen {{ ip }}:80;
server_name example.com;
root “/var/www”
}

Thanks
