Deploy nodejs app, but existing document root

I need to deploy a nodejs application, so I need to config a proxy pass with apache, the thing is that in that domain has already a document root with an autogenerated index (and I need a proxy pass instead). So i've been searching for the configuration file that set that document root for that domain, and I cant found it, the /etc/apache2/conf/httpd.conf file have comments that say that file is autogenerated and I should add files to /etc/apache2/conf.d/includes path instead. I've tried to write a file in the includes path to set the proxy pass but when I reload httpd.service the autogenerated index is still there I think that cpanel is writing in the httpd.conf file to set the document root, how can I stop cpanel doing that?
