the main command dial will be used to set aperture in

Aperture
setting
If Sub-command dial is selected, aperture can only be
adjusted with the sub-command dial (or with the main
command dial if On is selected for Change main/sub >
Exposure setting). If Aperture ring is selected, aperture
can only be adjusted with the lens aperture ring and the
camera aperture display will show aperture in increments
of 1 EV (aperture for type G and E lenses is still set using the
sub-command dial). Note that regardless of the setting
chosen, the aperture ring must be used to adjust aperture
when a non-CPU lens is attached.
