Looking at a Teardown of the nothing phone 1, it looks as if you may be able to remove the majority of the components and install them in a new frame, this can be a difficult process however, and it seems there may not be a lot of places for spare parts

there have been a few posts on repair communities and forms that are complaining that there are very few parts available for the nothing phones in General
I wish you luck, and hope you document your progress.
