The S-76 has a big disc brake bolted to the rear of the main rotor gearbox. As one of its minor functions, it appears to drive the tail rotor....

All models (IIRC)- start both engines to idle, brake on.

All (except B) models - stop rotor, with both engines at idle.

B model - stop rotor, with one engine only at idle, one stopped.
