Identify Provider Per OSF Cluster or Site

Summary:

We are enabling authentication in one of our sites and we currently have 3 OSF Clusters enabled per tenancy. The new Site would need to use a different Identify Provider than all other sites.

I would like to know if there is a way to set a separate Identity Provider for some specific Sites or OSF Clusters. This is crucial for us, since this new site will not use the same identify Provider and I was reading the Oracle's documentation, and it's seems it only supports one "single identity provider", but I was wondering why we have the endpoint like "/samlIdentityProviders/default".
