Does ih8sn hide the Know Warranty Void flag or the fact that the bootloader is unlocked from apps (some of my banking apps do not work anymore, but my phone is not actually rooted, so I think the issue is either the Knox Warranty Void bit or the unlocked bootloader)?

Using hadesROM 3.0 on a Samsung S8 G950F.

Once you unlock your bootloader (tampering the Knox Warranty bit), there is no way to spoof the result of a hardware-backed key attestation result, meaning that if the applications perform a HWKA by themselves (not via SafetyNet), there is no way to spoof its result. Many banking applications are adopting this approach, so it's up to how the application is implemented.
