( I saw that the DISM in Win-RE does not have the same params & switches as does Windows' DISM, lacking in particular the specification of a source.)
Whether you use Windows RE or run DISM in Windows, the options are identical. Unless your version of WinRE is out of date?
These are the switches available when running in Windows RE
DISM.exe [dism_options] {Imaging_command} [<Imaging_arguments>]
DISM.exe {/Image:<path_to_offline_image> | /Online} [dism_options]
{servicing_command} [<servicing_arguments>]
DESCRIPTION:
DISM enumerates, installs, uninstalls, configures, and updates features
and packages in Windows images. The commands that are available depend
on the image being serviced and whether the image is offline or running.
