I always turned the egpws off once visual in the valley at TGU Honduras. It always started going off on base leg next to the hills so was a distraction. It is much easier to turn it off at 3,000 ft rather than 400 ft on base leg. TGU made the second most dangerous airport airport in the world last week on that 2 hr history channel program last week. Once you see the terrain you don't need it any more. I wonder why they flew into terrain. It couldn't happen at TGU because everybody was looking out the window, not fiddling with automation.
