SSRS web portal url not working after adding a report server https binding.

I made a clumsy mistake and added a report server https binding to the web portal url in SSRS. I inherited this server and haven't touched ssrs in years.  sadly, it's a production box and I need to unbind that cert from the web portal url.  

What are my options to restore http://odin:80/reports. Is it as simple as unbinding the cert and removing the https url? procedure?    sweating bullets here. 

SQL Server 2017 running on Windows Server 2016.  IIS is not on this machine.
