ADE9000 shield kit design

The EVAL-ADE9000-Shield kit (UG-1170) has a ADUM6404ARIZ IC (U2) with VDD1 = 5V and VISO = 5V. The bpard kit has two SN74LV4T125PWR ICs traslators: U3  from  3.3V signals to 5V signals, and U6 from 5V signals to 3.3 V signals. To a similar design with the ADE9000, can the ADUM6404ARIZ IC works directly with VDD1 = 3.3V and VISO = 3.3V to eliminate the SN74LV4T125PWR ICs traslators?
