You want to know whether you can add the additional optional components during the creation of a preboot configuration for a boot disc or a PXE configuration.
Ghost Solution Suite (3.x)
While creating the preboot configuration from the boot disc creator, you can only install the default optional components shown in the screenshot below. Anything outside of this list are not able to be added.
It is not recommended to add every optional component only the components that are required for your boot environment. Winpe-enhancedstorage-package as an example is useful for systems that are using secure boot and can be added with out causing any negative interactions with other components.
