<p>The form alter using <code>form_entity_view_display_edit_form_alter</code> hides the entire form, but the 'Custom display settings' on the Default form is needed in order to enable other view modes for that bundle.</p>
<h4 id="summary-steps-reproduce">Steps to reproduce</h4>
<ol>
<li>Install Drupal CMS</li>
<li>Visit the Default view mode edit page for the utility page</li>
<li>See that you cannot enable a new view mode</li>
</ol>
<h3 id="summary-proposed-resolution">Proposed resolution</h3>
<p>Check for this on the form and don't remove it.</p>
