Pretty sure you can just disconnect it by unplugging one connector and not harm anything . . . . or easier yet, you could just cover it with a favorite photograph trimmed to fit - Maybe a pic of someone you'd like to spend a few extra years with when you finally get around to giving up your nicotine habit ?
My wife had one lung removed late last year, which has changed our lives forever . . . . but the good news is, she's still with me and may well be for several more years - We hope!
