NO...Have you lost your mind!!

If you just removed the NXT 2.0, there really shouldn't be any of it left to worry about, before putting DC Carnauba Wax on the vehicle.
Wait a minute...that's not right.
You just removed the NXT 2.0's "haze".
In an ideal World, it is said that you should wait at least a few hours (12 would be more like it) to allow this sealant the time to cross-link, before applying a carnauba wax on top of it.
Then again...
Often, time-constraints will not allow adherence to this cross-linking time rule. This is one rule that has been subjected to breakage on many occasions...sometimes even by me.
