No, adsons cannot do that kind of stuff (for reasons). There is just the keybind for "next target" which highlights the target you selrcted with a small aura.
Tab targeting is a white aura but I know when looking at npcs it can be white (friendly), yellow (neutral), or red (enemy). At the very least I know the healthbars and names can be turned on to be constant.
