I do not believe it is possible to disable them with normal means.
That said, are you sure you are hitting the paddles, and not just engaging the throttle kick-down feature?
The reason I ask is that this will cause a downshift at the most useless time possible.
If, on the other hand, you are sure you are hitting the paddles inadvertently, I could only recommend one choice.
Remove the airbag, and then disconnect the steering wheel wiring for the paddles themselves.
This might create a different issue, as I have no idea if it would create new warning lights.
Good luck finding a solution!
