Intriguingly, I didnt actually changed the Permissive Security Policy myself at all it seems that executing `csrutil disable` has the side effect of reduce the policy level to Permissive, and tuning the policy level up to Reduced or Full also force re-enabling SIP. Big Sur, however, will not allow me to install to an APFS-encrypted volume on the internal SSD, even after unlocking said volume, so its unclear whether thats a bug or design choice.

Although Big Sur uses the same protected System volume and APFS Volume Group as Catalina, it changes the way that volume is protected to make it an even greater challenge for those developing malicious software: welcome to the Signed System Volume (SSV). Im not saying only Apple does it. That seems like a bug, or at least an engineering mistake. The error is: cstutil: The OS environment does not allow changing security configuration options. 1.
