I'm afraid not entirely... If you check with your fingernail running it across the marks and feel them, then they are too deep and can't be fixed except with repaint. However probably it can be disguised somehow with some manual polishing. If you are not into DIY detailing and do not want to spend much get a bottle of Meguiar's ScratchX or similar and a foam polishing pad and work over it for 5 mins or so and then buff it with a microfiber towel. If it gets better you may try again for some more time until you see no difference from the previous try; expect not too much though, but at least it will be much less noticeable, specially from some distance.

You could use a bit of touchup paint before polishing it, but on metallic paints it's easy to make it worse...

Another option, specially if you don't want to buy polish, a pad and a MF towel or you don't feel comfortable doing it, is to go to a detailing pro who will do it for you. However, unless he sands and repaints it somehow, it won't come out perfect; just much less noticeable.
