Abstract
A disclosed method for provisioning an information handling system includes accessing a custom certificate database (CCD) including one or more certificates corresponding to one or more custom firmware features and generating a custom db variable for the CCD, which is subordinate to a default OEM db variable for the CCD. The custom db variable may be provided to a system BIOS residing in an SPI flash device. Responsive to the BIOS validating the custom db variable against a Secure Boot platform key, the custom db variable may be stored to a second NVM device. The custom db variable may be injected into a default Secure Boot db variable residing on the SPI flash. Prior to executing any of the one or more custom firmware features associated with the CCD, the custom db variable is verified with a certificate residing in the SPI flash.
