Hi Shimizu,
If your customer would like to use external varistors for external ESD protection this is not an issue, however our device is protected internally for the ESD specifications we have in table 6.2 on page 5 of the DRV8812 datasheet.
For most applications, this is enough ESD protection on the motor drive pin. If your customer would like to use these for their application that should not be a problem.
