That's silly.  Either it's your device, or it's not.
Even if it is in the wrong location, enrolling the device makes sense.
Unless it's completely the wrong *model* and hasn't got any interfaces of the
right type, getting the new service online usually takes priority.
Installing a $300 8-port firewall instead of the $200 2-port firewall isn't a
disaster. If the model was close enough, you'd want to consider the cost of
shipping vs the cost difference of the devices.

You might ship the *correct* model out once you figure this out and have
remote hands swap cables later on, but that's essentially a capital
allocation question.

If you know enough in advance to know which device (down to the SN) was
supposed to be in each location, then I don't think you need/have a zero-touch
situation.
