Changing ADXL362 supply voltage in Wake-up mode

Hi

 

I have done a design using ADXL362 and need to configure it for Wake-up detection. I have configured the activity and inactivity thresholds in referenced mode. The supply voltage changes when it is in inactivity/activity mode (from 2.0 to 3.0 and vice versa). This causes issues as on the activity/inactivity detection due to increased offset on the Z/Y/X components at 3.0V supply versus 2.0V supply voltage. How would you handle this?
