If the phone already updated (not sure, due to your wording), your only option to "get rid of them" is to flash the older firmware to the phone. (That gets rid of any changes made to the phone since it left the factory, so you have to back up everything first, then restore it after flashing the firmware.)
If you mean that it updated, but you're still getting notifications that there's an update, there probably is, so let it update again.
