Yes, it is possible. If you doing it in install script - you should set 'visible' to false:

$installer->addAttribute(Mage_Catalog_Model_Product::ENTITY, '<attribute_code>', array(
    ...
    'visible'       => false,
    ...
));

If you need change it for existent attribute directly in db - go to catalog_eav_attribute table, find your attribute (look for attribute id by attribute code in eav_attribute table) and set it's is_visible field to 0.
