TPMFirmwareUpdateSettings

Setting the policy configures availability and behavior of TPM firmware updates. Specify individual settings in JSON properties: * allow-user-initiated-powerwash: If set to true, users can trigger the powerwash flow to install a TPM firmware update. * Google Chrome version 68): If set to true, users can invoke the TPM firmware update flow that preserves device-wide state, including enterprise enrollment, but loses user data. * Google Chrome version 75): Controls how automatic TPM firmware updates are enforced for vulnerable TPM firmware. All flows preserve local device state. If set to: * 1 or left not set, TPM firmware updates are not enforced. * 2, TPM firmware updates at the next reboot after user acknowledges the update. * 3, TPM firmware updates at the next reboot. * 4, TPM firmware updates after enrollment, before user sign-in. Leaving the policy unset renders TPM firmware update unavailable.
