       tpm_setownable  -  change  whether  the  TPM  allows  tpm_takeownership


       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.
