DRV8870: Change VREF during operation

Hi all

Would you mind if we ask DRV8870?

Is it possible to chage VREF during operation?

As the background, the customer would like to change current limit as follows;
Operation start : 100% current limit for lush current
After operation start : 50% current limit after starting(normal current level)

In this case, does it have any deglitch time for changing VREF?

Kind regards,
