Two different pieces of equipment—the engine has it own set of limits, different certification and production certificates. The engine can be removed, replaced or have an AD against.

Correct, the HUD is required for using the EVS. The MFD is for F/Os awareness only. A dual HUD installation would get around this restriction. Still, if I were flying solo, it’d require a pretty dire emergency to make the arrival dependent on HUD/EVS minimums.
