Commercially and depending on how deep the scratches are it will either be very expensive or if the scratches are very deep it will be very very expensive.
You could try to find a colour match - cover the scratches yourself and polish it up with some metal polish but you'll just have a noticeable patch - you'll never achieve a blending in.
If it were my machine I'd make a feature of it - draw over the scratches with some design - put colourful stickers over the marks - or do nothing at all.
Good luck...
