Need to remove ADFS settings from Exchange

I was doing some testing and setup ADFS for Exchange 2019 OWA. Now I need to remove it. I have removed all settings from ADFS but still get redirected to the ADFS URL. It fails to do anything because all ADFS settings are removed but I can not seem to find why OWA is still being redirected to the ADFS URL. I see the set-organizationconfig but can not figure out how to clear those settings out. Putting $null in just gives an error.
Assistance would be greatly appreciated. Thanks!!

    Wow, you're awesome! I would never have guessed just having the auth method enabled with others still enabled would have forced ADFS.
    Thanks a million.

    Did you reverse all the virtual dir settings and restart IIS on the Exchange Servers?

    Thanks for the quick answer
    The only thing I did to the virtual directories was to enable ADFS authentication. I did not disable any of the other auth methods, just enabled ADFS auth.
    Thanks
