FreeSBC - Disable 1+1 setup

I have initially setup the FreeSBC with redundancy to test out the Pro feature. But now I need to remove the 1+1 setting as it should expire with the 90 days.

What is the necessary steps to remove the 1+1 setting so that it won't impact my Free Edition usage in the future?

Go through the initial configuration and select "As a stand-alone unit". You can run the initial configuration screen again from the following menu;

Host -> Status -> Select the primary host name -> Host Control -> Select Reset Host Role from Action Drop-Down menu
