I'll answer the, "Does disabling it void your warranty?" question. The answer is almost always "no". Unless the modification you make to something actually directly or indirectly caused damage to it, companies in the US cannot "void the warranty".
IIRC, this is under the Magnuson-Moss act but I didn't find it when skimming wikipedia.

The warranty is intact, but the device is bricked, because it can't bypass any of the authentication that is required to do... Pretty much everything.
