I'm not sure this is ideal - do Infineon have any Linux tooling for performing firmware updates, and if so will that continue working if the device is blacklisted? It's also a poor user experience to have systems using TPM-backed disk encryption keys suddenly rendered unbootable, and making it as easy as possible for people to do an upgrade and then re-seal secrets with new keys feels like the correct approach.
