$default_display = EntityFormDisplay::load('user.user.default');
$register_display = $default_display->createCopy('register');

The user.user.default form display is created by the "standard' profile, and it also exists in Umami.
Anyone running the minimal profile won't have it, so the second line is not guaranteed to work.

We'll need some boilerplate cause #2367933: Move entity_get_(form_)display() to the entity display repository was fixed only for Drupal 8.8.x:

    $user_form_display = EntityFormDisplay::load('user.user.default');
    if (!$user_form_display) {
      $user_form_display = EntityFormDisplay::create([
        'targetEntityType' => 'user',
        'bundle' => 'user',
        'mode' => 'default',
        'status' => TRUE,
      ]);
      $user_form_display->save();
    }
