I just noticed that when configuring Ekos, there are a number of cameras and mounts to select but not an INDI mount or INDI ccd like in PHD2. I would have thought INDI compliant devices would have been the default, and yet they aren't even listed.
All these devices you're seeing ARE INDI mounts and CCDs! PHD2 uses a generic term to denote that it is communicating remotely with either INDI mount or CCD, but in Ekos everything is INDI.
