New GVM installation on Redhat linux

Just installed GVM on RedHat Linux 8 and the default login is on port 80/443, not on 9392, I can not find where to find the httpd /apache config files to change it. Looks I don’t have httpd/apache installed on that box, what is the web server that GVM installed? I need to location this config files to change some things such as to disable the tls1.0/1.1 etc.

I have no problem locating the httpd config files on Kali Greenbone installation.

Thank you.
