Looking at the OP.

You want to remove some values for new entries, but allow them on current entries, or when an admin is editing. I would simply remove them from the front end of the site or based on other things. Removing an choice in a select field will not remove that value where it has already been selected.

add_filter('acf/prepare_field/name=select_field_name', 'filter_choices', 20);
function filter_choices($field) {
  if (is_user_logged_in() && current_user_can('administrator')) {
    // not for admins
    return $field;
  }
  // values to remove
  $remove = array(1, 2, 3);
  // get the current value of the field
  $value = acf_get_array($field['value']);
  // get all field choices
  $choices = field['choices'];
  // clear the field choices
  $field['choices'] = array();
  foreach ($choices as $v => $l) {
    if (!in_array($v, $remove) || in_array($v, $value)) {
      // this value should not be removed
      // or it might have been previously selected
      // so keep it
      $field['choices'][$v] = $l;
    } // end if keep it
  } // end foreach choices
  return $field;
}
