At this moment, the only way to enable it is by using a hook.
The reason we disabled bulk editing for the descriptions (or content fields) is that we did not see a use case for why bulk editing would be useful. You can use the following hook to enable bulk editing for the Short Description column.

add_filter( 'acp/editing/view_settings', function( $data, AC\Column $column ){
	if( $column instanceof ACA\WC\Column\Product\ShortDescription ){
		$data['bulk_editable'] = true;
	}
	return $data;
}, 10, 2 );
