Systems and procedures are provided for validating an IHS (Information Handling System) as operating using only factory-provisioned lockable devices. During factory provisioning of the IHS, a signed inventory certificate is uploaded to the IHS that includes an inventory of factory-provisioned lockable devices and also includes encrypted code(s) for accessing the lockable devices. Upon delivery and initialization of the IHS, the inventory certificate is retrieved by a pre-boot validation process. An inventory of detected lockable devices of the IHS is then collected. The validation process compares the collected inventory of detected lockable devices against the inventory of factory-provisioned lockable devices from the inventory certificate in order to validate the IHS is operating using only factory-provisioned lockable devices. If a lockable device is validated as factory-provisioned, the encrypted code included in the inventory certificate is deciphered using a private key of the customer in order to gain access the lockable device.
