Idcs url for local username and password login for Dual Idp

In our Idcs we have

1. OAM SAML Idp federated users
2. Local Idcs non federated users

For our app we have made Federated Saml OAM Idp provider default
We dont want chooser login page to avoid confusing users (which shows local idcs user login also side by side)
This setup works for Federated users as it always shows OAM login.

Pls comment - How to craft a url so that Non federated local idcs users can login via local idcs username/password ?

Local Idcs users doesnt have any "provider id" as it doesnt have any IdP provider

This one just shows the login for federated users.
