I'm not sure where all these misconceptions originate.
The DCC friendliness has nothing to do with powering the frogs. It is about having opposite polarities on parts of the turnout where they are close enough for the locomotive's wheels contacting bot pieces, creating a short.
In most cases (at least in N scale which I am into) this problem exists at the rails which exit the frog. Also if both points are hardwired together (have the same polarity) the back of the wheel can touch the open point (iff the distance between the open point and stock rail is not wide enough) causing a short.
Frogs are powered for reliability reason (
both in DC and DCC). I would say power your frogs.
These are all generic properties of turnouts in any scale. I don't know the specifics of the Atlas C83 H0 turnouts. If there is something quirky about these, maybe someone specifically familiar with these will chime in.
