In native WoW UI there was a setting to display nameplates for specific things like you could pick "Show Quest NPCs" but seems to be gone now? I liked that because it made quest mobs stand out nameplate wise amongst the none quest ones. So you only saw quest npc nameplates unless in combat. Unless I am just wrong, and it's still here but I can't seem to find it.

Is this something that can be added as a feature? I am sure there might still be a CVAR toggle for that maybe?

EDIT: Think I might be misunderstanding how it used to work, and investigating first.

EDIT: Nevermind, it's "names", and it wasn't working at first, but after resetting it's working again.
