Hi, is it possible to modify the driver’s seat to allow for a lower seating position?

I doubt you can change the rails or seat frame. Best see an car interior trimmer to reform your seat.

Heated seats may be a complication.

One option might be to try the seats in other Karoqs - for example the electric seats or Sportline seats may provide a lower seating position. I'm 6' 4" tall and and due to a neck injury 20 years ago have to sit quite upright, backrest not reclined much. The drivers seat is lowered but not to its lowest setting and I have plenty of head room. Its the first car I have owned in the last 30 years where the sun visor is actually needed. I have a Sportline which has the Sports seats and a Pan roof so maybe that helps'
