[Removing Buttons for Service Domains]

We have decided to use the "Links" for our service domains in order to have larger buttons for the end user. However, the service domain small font links in the top right are no longer needed. Does anyone know how we might be able to remove these? Thank you!

[New SSO Questions]

Is there a way for us to keep our Integrated Windows Authentication as the mechanism for agents to sign in?

Will the new log in screen only appear for agents or will this also happen with end users using the portal? Thanks!
