Help Center: End User Authentication - Bypassing SSO/SAML

Background:
I have a question regarding Help Center "End user" authentication. We have two categories of "End users":

A.) Internal <our company> product users that we want to authenticate via SSO/SAML

B.) External paying <our company> product users that we want to authenticate with Zendesk authentication (Email address and password)

Question:

Is there an alternative Help Center URL similar to the Support service where a user is allowed to bypass the SSO/SAML authentication?

For the Support URL, we can append "/access/normal" to achieve the goal of bypassing SSO/SAML authentication.  Such as "https://your_subdomain.zendesk.com/access/normal".  But this same strategy does not work for the Help Center, appending "/access/normal" to our Help Center's URL.

We are seeking a similar option for the Help Center service.
