How to remove previous stateflow observer before adding new one

Question

what if I'm calling below method twice in loop? does it gonna call onEach method twice. the app driver flow is returning AppDriver object

private fun getDriverObj() {
        homeRepository.getAppDriverFlow()
            .flowOn(IO)
            .onEach {
                appDriver = it
                checkRequiredObjects()
//                signalRController.
//                signalRController.stopSocket()
//                signalRController = SignalRController()
            }
            .launchIn(CoroutineScope(IO))
    }
