The factory alarm cannot be disabled as it is linked to many other components such as the central locking etc.
For the alarm to go off randomly, the cause are usually the door or hood switches. Check if any of the doors are out of adjustment or door switches rubber cover are missing.
If any of the door ajar indicator is intermittently blinking, that is the door that the problem is coming from. If they do not occur, the most likely source would be the hood switch.
