Is it possible to hide fields on node edit form or split node edit form in two screens?
You could use different modes on the two routes. Go to /admin/structure/types/manage/fooxx/form-display and there you can configure which fields you want see on which mode.

You can add new modes here: /admin/structure/display-modes


  Note: While Drupal 8 core already comes with "form modes", in Drupal 7 you need to install the
  flexiform module.
