Is it possible to change delivery to in store pick up?

I ordered the ipad pro 2020 when it was out of stock and the estimated delivery time was about a month to a month and a half away. However, when I checked it today, I saw it was available and no longer out of stock. I was just wondering if it is possible to pick it up in store instead without cancelling my order (as a part of my order already came) or whether the date of my ipad arrival will change as a result of the re-stocking of the ipads in the stores? It might sound pretty impatient, but I was just wondering about the possibility of it.
