Tuya based dehumidifier: only limited humidity settings available

I have a Tuya based de-humidifier (Stadler Form Lukas) which was automatically discovered by the Tuya integration. It’s working fine so far. Except for the fact that the target humidity can only be set to 30, 40, 50%. I’d prefer 55 or 60%. Is this a limitation of the device which can be overcome by tweaking a configuration file?
