Remove all ADFS configuration from SharePoint

Hello,

We have new SharePoint farm with ADFS 2.1 farm (so farm ADFS + PROXY) installed and working.

One of our requests is to change signing certificate so we could sign in using different URL.

I found it very confusing to change these certificates, so instead I would like to reinstall ADFS configuration with newly certificate. To do that, I must "remove" all my SAML Provider configuration from our SharePoint farm (correct me if I'm wrong).

How can I achieve my goal?

Thanks
