       tpm_setownable - change whether the TPM allows tpm_takeownership operations


       tpm_setownable [OPTION]


       tpm_setownable reports the status of the TPM's flags regarding if the TPM can be owned.
       This is the default behavior and also accessible via the --status option. Requesting a
       report of this status prompts for the owner password.  The --allow option sets the
       system's TPM to allow tpm_takeownership operations (via the TPM_SetOwnerInstall API).
       This operation requires physical presence.  The --prevent option (via the
       TPM_SetOwnerInstall API) prevents the TPM from accepting tpm_takeownership operations.
       This operation requires physical presence.  These operations are persistent.
       tpm_takeownership requires the tpm be enabled.
