You can find an amazing amount of detail in your "My Volkswagen" page. Extracting my electric motor details I get
Electric motor unit 0EH.A
Electric motor, total system output 150 kW base motor is N06/N07
Torque 310 Nm Base motor is N06/N07/N10
So I doubt it will be as simple as a software update, though I could see after market motor upgrades being a thing using salvaged parts, but why bother?
