This isn't always clear - some jack detection is implemented entirely by integrating simple components like GPIOs and ADCs or by integrating limited support in one device with some external components to get more features (like bolting an ADC on the side for button detect). I would not expect to ever see a device with jack detection support that could just be unconditionally enabled, it will always require some board level wiring up to provide the connections required to function.
