I don't know. As this setting would only be changed when wiring and/or breaker are physically modified (it governs the maximum draw), and they'd want to avoid this switch being exposed to the elements, it's probably not easily accessible, and shouldn't be.
Anyway, it was really easy to get this information - I just called Lucid, stated I was a reservation holder, and was quickly introduced by email to the right person. They are now in contact with my electrical contractor so my wiring installation is done to spec.
