questions about my new truck

I have a couple of questions about my 2016 Frontier:

Is there a way to program the locking mechanism Not to unlock when I shift into park?
Is there supposed to be a warning chime if the seat-belts are not fastened in the front seats?
Is there a way to have the fuel door stay open when opening for fuel? Mine keeps closing?
When using the key fob to lock the truck it always beeps the horn once. Can this be changed to just flash the lights?

These are some things that I have programmed on most of my other cars.
