How to change modes with the KD V2 driver?

Not that I know of. However, I use that kind of driver very often, you'll get used to it :)

If you are good at soldering, you could try mod a NANJG105C as described somewhere here, i.e. solder some components and reprogram it with Tido's firmware, because it's able to work with that mod. Maybe you could ask someone who did that already to do it for you.
