I don't want to unplug the valves, this is my first performance car and im car broke because of it lmao so I can't risk voiding a warranty or breaking something

I want to use BimmerLink but I don't think it can code the exhaust valve open (I don't even mind if I have to manually do it with my phone everytime I get into the car)

I know valve controllers exist but they are expensive and also tamper with the hardware of the car (installing extra components to already existing mechanisms)

Any insights, advice, or recommendations? This car is too quiet!!
