No sorry that was the indicator only,
TERRAIN SYSTEM Panels
Located at each main instrument panel (3VU, 5VU), the TERRAIN SYSTEM Panels contain the controls used to operate EGPWS Terrain Clearance Floor, Terrain Look-ahead Alerting functions and the Terrain Look-ahead displays. The TERR DISPLAY Select Switchlights allow each pilot to select the Terrain Awareness Display onto his or her respective Navigation Display. The TERRAIN OVRD/FAULT guarded Switchlights allow each pilot to override the EGPWS Terrain Clearance Floor and Terrain Look-ahead Alerting functions; GPWS Modes 1-6 are not affected. The FAULT indicator illuminates when a Terrain function fault is detected.
TCF though could have been inhibited.
