how to add custom httpd.conf code only for https traffic

I want to configure a custom domain for a helpdesk service and figured out how to edit the specific httpd-config file but...run in some errors regarding the SSL-certificate.

This is the part of the help-file I followed.
Everything is working perfectly when I just edited the users httpd.conf file. Of course this is not the right way to do it...but when I'm using the "Custom httpd.conf code" feature of DirectAdmin, the specific lines will also be added to the virtualhost that is set up for the http-connection. I don't want that, since that traffic will be redirected to https.

Hopefully you can help me with this, setting it up the way it is supposed to.

Kind regards, Walter
