I have used PEAP and EAP-TLS successfully before. It isn't really hidden, it is under connect to other network If NM detects a network using EAP then the PEAP or EAP-TLS options are shown. If your network is not broadcasting and you need to select the options manually you will need to select connect to other network so I /think/ all the places you would need to find it are covered.
