Do not attempt to remove the TPM plug-in module from the system board. Once the TPM plug-in
module is installed, it is cryptographically bound to that specific system board. Any attempt to remove an
installed TPM plug-in module breaks the cryptographic binding, and it cannot be re-installed or installed on
another system board.
