Answer 1

Through location, refer to the desired file, and there, through add_header, add the necessary headers.
For example,

location = /myfile.json {
  add_header 'Access-Control-Allow-Origin' '*';
}

Keep in mind that the add_header declaration in the location block overrides the headers declared in the server block, so duplicate them if necessary.
