Looking at one indicator for engine parameters seems pretty intuitive (FLI)
The “secret menus” are not secret, they are easily accessed. The ones you need in flight are accessed with one button (scroll), and
the other screens are to get to Overlimits, previous power checks, failure diagnostics etc. There is no need to access these in flight, though they have proved to be very useful for their intended purpose.
The Fadec would operate just fine with a total VEMD failure.
All the best

I suspect what he refers to is the autopilot power limiting, with coupled collective - that does get affected, and if the IAS is set too high, can result in a big overtorque. But, I disagree with his sentiments in general
