The KORE CF crank arms are boxy, so the "aero" ring is not gonna make one tiny bit of difference.
the "aero" rings i've seen are for track bikes, and mainly just one stamped sheet of aluminum with no cutouts.
the interface is three screws holding the ring to a spline... like most direct mount rings/cranks that don't use a retaining ring.
the screws don't carry any torque load, just the splines.
