If you manage to pair it sucessfully with the ZHA integration then chances are good that it can be made to work even if none or not all attributes are exposed as entities in ZHA, but it means that the device will probably need a custom ZHA Device Handler (also known as a ZHA Quirk) coded for it in order to expose Zigbee clusters and attributes are not exposed as standard by default, however you either need to code such a custom quirk yourself or request device support hoping that someone else can help coding of a zha-quirk for it. See:
Also read the section above that for additional information on why custom zha device handlers are not needed for all Zigbee devices:
And some additional info here on what to do once a custom device quirk is written:
