I don't have one of these,so going off of the documentation here.
What firmware are you on? Maybe that would help to update. ZEN27 S2 Dimmer Change Log - Zooz Support Center
And I think Parameter 18 would help. ZEN27 S2 Dimmer VER. 3.01 Advanced Settings - Zooz Support Center
You can set parameters by using the Hubitat Basic Zwave tool if it isn't exposed in the driver.
