This depends very much on the storage temperature and humidity. If, for example, the nuts are dried in a (conventional) warm and dry boiler room, this may well be sufficient. If this is not sufficient, you will notice this in the oil press, as nuts that are too moist will clog the appliance. In this case, the nuts must be dried again in the oven for a while before you can continue working.
OP 700 - Is it possible to dry walnuts by storing them (without using an oven)?
