You have it. Option S2VH - Integral Active Front Steering. I don't know why it is called Integral Active 'Front' Steering in all VIN decoders, but that is the correct option there.

Integral active steering doesn't only mean rear axle steering, but also variable ratio steering. There is a different, variable geometry front steering rack with this option as well. Whether it is 12V or 24V rack depends on the vehicle variant. Without S2VH option, you have a fixed steering ratio along the steering wheel movement. With S2VH, the steering ratio adjusts depending on the steering angle and is more indirect at center position.

EDIT: Attached the functional and technical documentation regarding standard EPS and HSR (Integral Active Steering).
