I've heard/read a few people say that it's possible to "unpatch" an ipatched Switch, by replacing the patched chip with a non-patched chip. I haven't heard anyone say where or how you'd get said non-patched chip. No, I don't remember who said it, but it was a few, different people. Most of it was regarding if someone accidently implemented "autoRCM" on an ipatched unit. This would result in a fully bricked Switch. To which they said the *only* fix would be a hardware fix, to replace the patched chip.
