如何删除<Module> ViewQuickcreate默认按钮？

From a QuickCreateView I want to remove the defaults buttons SAVE, CANCEL and FULLFORM. I got to do it modifying the core file /include/MVC/View/views/view.quickcreate.php in method display by commenting the following lines

$this->ev->defs['templateMeta']['form']['headerTpl'] = $this->headerTpl;
$this->ev->defs['templateMeta']['form']['footerTpl'] = $this->footerTpl;
$this->ev->defs['templateMeta']['form']['buttons'] = $this->defaultButtons;
$this->ev->defs['templateMeta']['form']['button_location'] = 'bottom';
$this->ev->defs['templateMeta']['form']['hidden'] = '<input type="hidden" name="is_ajax_call" value="1" />';
$this->ev->defs['templateMeta']['form']['hidden'] .= '<input type="hidden" name="from_dcmenu" value="1" />';

But I want to avoid this. What is the right way to remove default buttons from ViewQuickcreate?
