Yes that's an easy one.
Using VAG-Com, dive into the instrument cluster
You will see a seven digit number against the coding.
The pen-ultimate digit is the one that does the seatbelt warning.
Mine was originally 4 - which means seatbelt warning for driver and passenger.
I changed the vale to 1 - so now I get a warning for driver, but nothing for passenger.
You could change it to 0 - which would give you no warning at all.
So to summarise:
17 instruments =>
recode module 07 =>
* started 2049443
* changed to 2049413
Hope this helps!
