how to turn off noise cancellation

hi, I just purchased the Razer BlackShark V2 with HyperClear Cardioid and integrated sound card, I'm trying to understand how to deactivate noise cancellation when needed since in certain moments I need to hear what's happening around me, my children, my wife or the doorbell, I downloaded synapse but I don't understand where I can find the setting to cancel the noise cancellation when I need it, can you tell me how to do it
Thank you
