CLI options are very broadly scoped.  For instance, with
transformations, we have a dedicated procedure to turn them into a
transformation that can more easily be used inside a manifest.  On the
general side…

… every command is available also as a Scheme procedure that takes its
arguments as a list directly.  Thus, you can quite easily transform the
above to 

(use-modules (guix script shell))
(guix-shell "-m" "manifest.scm" "--container" "-F" "-N" …)

Of course, if you want to dig deeper, you can also call the functions
guix-shell ends up calling, but whether doing so makes sense is up for
you to decide.

Happy hacking!
