How can I force a user to use a different SSO IDP for a portal if they are already authenticated ?

How can I force a user to use a different SSO IDP for a portal if they are already authenticated with another SSO IDP within the instance?

We use 2 SSO IDP for our instance.

Some users have the option of using both.

However, for some of our portals or for the backend, we would like to enforce the use of one or the other.
Is it possible to force authentication via one of the two, even if the user is already authenticated via the other?

Thank you in advance.

Thanks, it can help, but i need (I think) to test/check somewhere (during the login step - on the login page) if the user is logged AND if yes, if the IDP is the same used on the current portal.
