I agree with Nicely, why not get a professional bodywork guy to cut out a secton of your carbon dash so that the SRS unit is still free and not covered.
To disable the srs from firing you must first disconnect the battery and remove the rear dogseats. There you will find in the centre the master control unit/ accelerometer/ g-sensor. Unplug the side that is connected to the passenger side.
Alternatively, though not recommended you may also try prying open the SRS airbag cutout, carefully so that the module is visible. There will be a switch of some sort, just unplug that. However many people discourage this idea because there's no gurantee that the airbag may fire again in the future.
Im converting my dashboard soon to the satnav spec one so i'm also looking at ways to get about this problem. And from other forums and chats with friends the former is the preferred way to go.
Cheers. And safety first.
