Can we expect firmware updates that includes the Secure Boot certificates for legacy platforms such as EliteBook 840 G5 and G6?

For EliteBook 840 G6 we have published BIOS version 01.35.02 (sp173290) which allows Microsoft adding the 2023 certificates on this system. For EliteBook 840 G5 (and older systems) which have reached end of service date there's an update package available which manually adds all the 2023 Secure Boot certificates to the KEK and db database. Please keep in mind the this package does not update the default databases. Please contact HP Support to receive the update package.
