CloudHealth has the ability to access via API to delete the SSO information.
This can be done with the client_api_id parameter and both customers and partners.
It may be necessary to ensure the API key is on hand and know the API DELETE call beforehand. Additional details can be found here:

Once SSO is removed any users configured in that tenant will then be able to log in to the platform directly.
