You can "disable" the port by removing its configuration from either the DIAL PLAN or the DEDICATED MAPS (whichever location you have it configured). Once it is removed from the DED MAP or DIAL PLAN, the front panel alarm should clear. You will still see the alarm if you go under MODULES and look at the ALARM STATUS for the module, where you can see all the ports, but the module status shouldn't show an alarm.
Hope that makes sense,
