In D6 and D7, with a simple form_alter you could unset $element['format'], but now the format help and the format tips are added in a #process method.

How can I remove them?

  • Form alter and replace the #process callback with a custom one maybe?

Apparently you can't hook into the #process phase, but you can still do a #pre_render, from /Drupal/Core/Render/Renderer.php

// If the default values for this element have not been loaded yet, populate
// them.
if (isset($elements['#type']) && empty($elements['#defaults_loaded'])) {
  $elements += $this->elementInfo->getInfo($elements['#type']);

// Make any final changes to the element before it is rendered. This means
// that the $element or the children can be altered or corrected before the
// element is rendered into the final text.
if (isset($elements['#pre_render'])) {
  foreach ($elements['#pre_render'] as $callable) {
    if (is_string($callable) && strpos($callable, '::') === FALSE) {
      $callable = $this->controllerResolver->getControllerFromDefinition($callable);
    $elements = call_user_func($callable, $elements);

For example, to hide the element format of the body field of an article:

 * Implements hook_form_alter().
function mymodule_form_alter(&$form, &$form_state, $form_id) {
  $form['#pre_render'][] = 'mymodule_form_pre_render_body';

function mymodule_form_pre_render_body(array $element) {
  foreach (Element::children($element) as $key) {
    if ($key == 'body') {
      foreach (Element::children($element[$key]['widget']) as $widget) {
        $element[$key]['widget'][$widget]['format']['#access'] = FALSE;

  return $element;
