The metal edge is scratched

To answer your question, yes, that metal edge can be replaced, but the bad news is that it's part of the midframe housing; the part that holds all the rest of the phone parts. So in order to replace it, you have to completely gut the phone; remove every single component inside along with the screen and transfer it all to the new midframe. Certainly doable, but doubtful it's worth all the work for a cosmetic issue. I'd definitely go with @danj's suggestion first of trying to sand it down and polish it out before going that far.

However, if you're really determined, the part is available online on many sites, both aftermarket and genuine Google parts. The genuine parts look like they're running about $120 USD, while aftermarket versions I saw as low as $27. You'll also need a ton of adhesives; you can get them in precut sheets for the screen and back cover, and there's a bunch of stuff inside like the battery that needs those too.

The Pixel 10 Pro Repair Manual has been added to the device page so you can look up the official Google instructions on how to replace that part.

I didn't find any tutorials online for that repair, given your phone is so new it's not surprising. The closest I came was the a teardown video that will actually get you most of the way there; you can find it on a YouTube video here.
