Is it possible to somehow adjust the conditioned floor area in OpenStudio?

By default the conditioned floor area equals the total floor area.

Don't add any HVAC system serving the zone.

See the DetermineBuildingFloorArea in

if ( Zone( iZone ).isPartOfTotalArea ) {
        buildingGrossFloorArea += curZoneArea;
        // If a ZoneHVAC:EquipmentConnections is used for a zone then
        // it is considered conditioned. Also ZONE SUPPLY PLENUM and ZONE RETURN PLENUM are
        // also is considered conditioned.
        if ( Zone( iZone ).SystemZoneNodeNumber > 0 ) {
            buildingConditionedFloorArea += curZoneArea;

I think you're using IdealLoads given your other question. Just don't enable ideal loads for these zones too.
