Looking at the list of parts and part numbers in the screenshot below, it seems to suggest the glovebox door isn’t available as a separate part. It might be worth checking with the parts department at your local dealer.

As an alternative to replacing the glovebox door, if the scratches are superficial and not deep, is it possible to improve the appearance of your existing door by using a suitable plastic dressing product? - it’ll certainly be cheaper than replacing the door. I’ve not used a plastic dressing product to hide scratches so can’t vouch for how effective such a product would be - maybe other forum members have and could post details of the specific product(s) they used and the results.
