NO the operator CAN NOT scan the film at a lower DPI to make the job go faster. Both noritsu and fuji equipment scans the film at 300DPI per output size. Are you losing something compared to a perfectly made optical print? Probably....but unless you plan on printing color in your darkroom, or shelling out $$$$$$$$ a competent lab operator on a digital noritsu or fuji will churn out better results than their optical predecessors which used a zoom lens to accommodate different print sizes, were hard to focus/insure perfect focus/had incredible light source drift after a short amount of time.
