How to disconnect F12 valves?

Hey guys, how are all of you doing? As all of you know, the F12 comes pretty quiet when stock and valves rarely open during casual city driving. I was wondering if any of you guys know how to easily disconnect the F12 valves. Could I simply remove the part of the diffuser by the muffler and disconnect the vacuum hose? Pictures would help! Thanks all!

 

Just remove the rear under plate. You can then see and feel both valves. Unplug and cap them off with something.

 

Thanks! By rear under plate do you mean the plate more toward the centre of the car, or the diffuser/muffler area?

 

I purchased recently an used F12 with low mileage which I'll receive next month and the car was used by Ferrari between 2014 and 2016 to be shown in auto saloons, etc. It's equipped with all possible features and next to the key there is a small remote control which enables the exhaust valves to be open or closed at will. As far as I know the exhaust is a standard one and they've installed this system into it. I've heard the animal with the valves open and my goodness the only word that comes to my mind is formula 1.
