From the Sensors section of the Details menu, you can see if a humidity sensor is installed. If a humidity sensor is set to something other than Not Installed, and the Dehumification Enable parameter in the System Configuration section is set to Enable, the option for dehumidification is present.

When dehumidification is present, the unit cycles the cooling to maintain a dehumidification setpoint. If the cooling begins to overdrive the zone temperature, the heating cycles on to maintain zone temperature. You can choose to use a hot gas bypass coil as reheat. When the system is configured as staged cooling with reheat, it energizes whenever a dehumidification call is present. If configured as a heat pump with supplemental heat, the hot gas bypass is energized when a dehumidification call is present and a supplemental stage is requested.
