Using TpmSecurity feature
This feature allows you to control whether the Trusted Platform Module (TPM) in the system is enabled and visible to the operating
system. The TpmSecurity setting is a master switch for all the rest of the TPM elds. System restart is required after changing the
TpmSecurity setting.
• Enabled — BIOS turns on the TPM during POST, and the TPM can be used by the operating system.
• Disabled — BIOS does not turn on the TPM during POST, and the TPM will be nonfunctional and invisible to the operating system.
NOTE: Disabling this option does not change any settings that you may have made to the TPM, nor does it delete or change any
information or keys you may have stored there. It simply turns o the TPM so that it cannot be used. When you re-enable this
option, TPM works exactly as it did before it was disabled.
TpmActivation: Activates and enables the TPM normal state for TPM use. TPM Activation is a setting which is available when the
TpmSecurity is enabled.
• Enabled — Activates the TPM.
• Disabled — Displays the current activation state of the TPM.
NOTE
: Disabled is a read-only possible value. TpmActivation can be disabled only from the BIOS setup screen.
Example: To enable TpmSecurity.
Set-Item -Path DellSmbios:\TpmSecurity\TpmSecurity "Enabled" -Password <Plain text password>
NOTE
: Restart is required after changing TpmSecurity setting.
Example: To enable TPM Activation. TPM Activation can be enabled only if the Tpmsecurity is enabled.
Set-Item -Path DellSmbios:\TpmSecurity\TPMActivation "Enabled" -Password <Plain text password>
NOTE
: Admin password must be provided and TpmSecurity should have been enabled to enable the TpmActivation.
Desired State Conguration (DSC) for Dell Command

Desired State Conguration (DSC) is a management framework provided by Windows PowerShell that allows administrators to monitor
conguration drift, manage registry settings, groups, user accounts, and environment variables, through a seamless way of scripting.
Dell Command | PowerShell Provider uses the DSC functionality to provide a solution that monitors the BIOS conguration on Dell client
systems and maintains the Dell BIOS settings that have drifted away from the desired state conguration. Dell Command | PowerShell
Provider provides a set of custom resources aligned to each category of BIOS settings and oers the user a declarative framework to use
properties (attributes) dened in the resources.
