You could try manipulating the VAV CO2 demand ventilation methods to make sure you are ventilating at set maximum rate of the terminal damper even though the setpoint and ODAmin requirements have been reached.
Otherwise, consider
FanPerformance:NightVentilation
in combination with
AvailabilityManager:NightVentilation
but I think this limits you to a two speed fan scenario.
