Supply AD7766 VDRIVE while AVDD/DVDD not supplied

Is it possible for the AD7766 to keep the supply on VDRIVE with 1.8...2.2V and leave the pins AVDD and DVDD unsupplied.

The 2.5V supply via LDO is switched off. This is mandatory in our project to minimize the overall supply current of the system in sleep mode. What is in this situation the input current in VDRIVE ?
