Set login option for agents (Admin)

Admin would like to request an option to set the agent login option and remove all of the others in the RC app. They would like to disable the options that are not used by their company.

"Is there anyway to disable the other login options of our RingCentral app? We use the username and password option. If we could customize the installation to only show the username and password option or if that was at least the default option it would be easier for our user's."
