That sounds right ... I mean should be no potential for them to deploy if you removed the fuse and and power. Make sure to wait for any residual power to drain, resistors and what not along the circuit path can hold a small charge. But I also want to say do not take my word on it not like I have done it.
I do not know if you are on good terms with your service center but is there any chance you could get their assistance or direction in removing/disconnecting the steering wheel. I got them to help with my lights originally for free and just asked nice and brought some timmy's in for them, I knew the steps but was unsure/paranoid about breaking clips so it was helpful to have a guiding hand, I did all the work they just pointed out how and where to pull that sort of thing. Your service manager/adviser should certainly be able to look up the 'OEM' steps for you at minimum. That is what I would do myself anyway.
