You need not disable it. If any errors had been detected, the airbag system self disables and triggers the indicator light.
Replacing the airbag sensor would not trigger the the system as it is programmed to activate only under vehicle moving conditions when any impact on the sensor occurs.
After installation of the sensor, if it is bad, the indicator light would not go off even if you reset it.
