RE: Latitude 7480 - Thunderbolt 3 - Thunderbolt software say external GPU support not enabled?

For what it's worth, the Akitio Node GPU enclosure recently received firmware that allows it to operate even with systems that say they do not support external GPUs as long as the Thunderbolt firmware on the system is NVM 18 or newer, and the 7480 just recently got Thunderbolt firmware available that's newer than this.

I'm not sure what it takes for the system to be recognized as "officially" supporting external GPUs and why Dell systems claim they don't.  One possibility is that Dell just doesn't want to deal with issues created by customers not understanding that they can't hot-unplug a GPU enclosure the way they can with most other Thunderbolt 3 devices like dongles and docks.
