It's fine browish I could help you. I don't know of the Switch console, nor homebrew apps. I'm a PSP, iPad and Pc gamer barely trying CWCheats. Sorry
In order to "unpatch" RCM we would need another RCM exploit that allowed some sort of code execution. The RCM firmware isn't accessible from anything other than RCM mode itself.
First of all RCM is in read-only, non writeable memory. That's why it cannot be patched even by Nintendo.
I put "unpatch" in quotes because it would just be a temporary on the fly patch that would require code execution to do in the first place. It might not actually be that useful if we had a RCM code execution exploit, as we might just be able to do what we need using that alone.
From my (probably incorrect) understanding it would be possible to edit the bootrom if you could get code execution before ipatch fuse lock out. I *think* the boot ROM checks if FUSE_ODM_LOCK is burned and then disables writing to the ipatches. If you could make that check fail ipatch writing would be enabled. That might be possible via fault Injection on Erista but on Mariko there's probably random timing to mitigate it. It would require a mod chip making the entire thing pointless anyway though.
