Found a manual for it, you should have a paper copy that came with it so you can confirm the setting:

Looks like you need to change parameter 5 to 0
You will need to use the Basic Z-Wave tool to set the parameter, but since it is a battery device you will need to coordinate waking it up and then setting the parameter within a few seconds.
Instructions say to press the button once to wake it up. Super basic Z-Wave parameter tool
