someone with more knowledge than me will hopefully chime in with specifics, but i believe there are manufacturer defined restrictions for lacing patterns and spoke counts on powertap hubs to ensure accuracy of power measurements. I don't recall what the restrictions are or what models they apply to, sorry.
perhaps the kids in the wheelbuilding thread could answer with specifics?

mentok is right - there is a 2x min spoking for G3s
I actually recently had built:
- 38mm tub carbon rim
- P'tap G3, 24h rear
- 2x NDS and 2x DS with DT Aerolite spokes
Wheel feels stiff enough. I would say similar to Boras - i.e. not super stiff but certainly good.

Stiff, Light, Aero - Pick Three!!

PowerTaps require a minimum of 2x. Radial lacing will void the warranty.
FYI I have both my G3 wheelsets built with 24 spokes and 2x on ENVE 45 and H Plus Son Archetype. The G3 builds a great wheel, much better than the previous generations. I can definitely tell the difference between the G3 and my old PT Pro wheels in terms of stiffness. Have fun with the build

It's funny how misinformation gets propagated. Many years ago Saris had a requirement for... actually 3x both sides... but it has been 2x on the NDS only for awhile now.
Per the G3 manual: "IMPORTANT: For your safety, the non-drive side of the PowerTap hub must be built with at least a 2x lacing pattern. Because of the patented PowerTap design, torque is
transferred through the hub to the non-drive side. Failure to adhere to this precaution will void the warranty."
But I'd never lace the DS radial. *If* you have derailleur clearance, you could lace the DS 1x heads-in. If not, best do 2x both sides. Using lighter NDS spokes will reduce the chance of them going slack.

The latest specs on the website say "Hub must be laced with mimimun(sic) 2X pattern." I take that to mean both sides.

The previous gen ones could be laced radial on the DS. I don't prefer doing that in any case.

My 2x wheels are my favorites. 28 holes and bomb proof.
