Unfortunately that's not the case, as the documentation says:

The code says it too:
(when (and content-length
(not (or (arrayp content)
(listp content)
(eq content :continuation))))
;; CONTENT-LENGTH forces us to compute request body
;; in RAM
...)

I tried that too, but:
(when (and (eq content :continuation) content-length)
(error "CONTENT-LENGTH must be NIL if CONTENT is :CONTINUATION."))
I think I might be out of luck.
