How to remove rowactions buttons ?

I want to remove this button and add another, but the issue here is even when I remove all buttons from the rowactions array still down 2 items appears

code example:

 'rowactions' => array(
        'actions' => array(
            array(
                'type' => 'button',
                'css_class' => 'btn show-filter',
                'events' => [
                    'click' => 'list:showFilters:fire'
                ],
                'tooltip' => 'LBL_FILTER',
                'icon' => 'sicon-filter',
                'acl_action' => 'view',

            ),
            array(
                'type' => 'button',
                'css_class' => 'btn show-download',
                'events' => [
                    'click' => 'list:download:fire'
                ],
                'tooltip' => 'LBL_FILTER',
                'icon' => 'sicon-download',
                'acl_action' => 'view',
            ),
        ),
    ),
