The Variable Vane turbos don't have a wastegate, the angle of the vanes, controlled by the vacuum capsule or electronic box, determines the boost pressure. I can imagine the electronic version adjusting the vanes to increase boost but on the vacuum capsule version there must be some way the ECU adjusts the vacuum pressure.
