Some do, some don't it's up to the company. And yours might already be tuned and all but I don't know.
Detuning is basically rounding off the edge until it's basically as dull as it can get. This is always done on the nose and the tail. They don't in any way affect the motion of the board except if they catch an edge which is always a bad thing. This is why they are detuned, to prevent/eliminate catching an edge/
ETA: I just looked into your board a little and I couldn't find anything on the edges yet. But it does have a sintered base. Sintered bases are a little heavy on the maintenance side. They absorb more wax, but they also lose it faster.
