Some switches/dimmers have the option to disable local and/or remote control (colloquially, some people loosely call this disabling the relay, regardless of the underlying electronics). In the manual for apparently the newest version of this device, I don't see a Z-Wave parameter for that or anything about local or remote protection. However, I know Zooz added this to their entire line a while back. A community (now staff) member managed to apparently find the correct docs, unlike me, and wrote a driver that should have options for what you're looking for:
If you don't want to use a custom driver full-time, you could also use the Basic Z-Wave Tool to set this specific parameter (parameter 11, size 1, to 0, it appears) and keep using the built-in driver for regular use. Otherwise, the above should have the options you want.
Finally, it sounds like you already know this part, but you would then have to create automations based on the button (Z-Wave scene) events to manipulate the lights as desired.
