Reassign tft pin

So in fact i need to re-assign LCD_D1 because it's PWM pin and i need 3 of them..
So far i got 2 PWM pins but i really need a third one.
The 9 would be perfect because i already use the 10 and 11 but any other PWM pin would be fine for me.

I've linked the shield to the arduino uno with small wires altough it's recommended to connect the shorter way.

That would be really nice if you could write me a special but if you could help me understand how it works that would be great, anyway if it's too hard to explain shortly, i would understand if you don't wan't to teach me.

Have a great day.
