How to walk off ledge (bypass fall prevention)

In Just Cause 3, there a undocumented keybind that turn off the fall prevention temporary.

This was tested with Default Keybind

All you have to do is walk to any edge that stop you, Hold Z (on keyboard) or Hold Y (on Xbox controller) and continue to move off the edge. And TADA, you finally fall down the edge without jumping.

Since this is tested only in my game, I need help testing if the fall prevention can be turn off without holding any keys.
Please comment if you found any other ways!
