I am pretty sure this is not directly possible right now.

Some approaches that resemble it could be:
1. write a src block that will be tangled to a script.
2. tangle the block
3. Run the script in a shell src block with an & so it runs
non-blocking.

or, use an elisp block like:

(org-babel-tangle)
(async-shell-command "your script" some-output-buffer)

I don't know a way to get continuous updated output in an org-buffer
though.

I do things like this by making code blocks that submit scripts to a
queue system if needed, and then raising an exception. If not needed,
the scripts read data files and return the answer I want.

You might find a way to use the async module
(https://github.com/jwiegley/emacs-async) to achieve something like this
too but I suspect it still involves tangling, or calling the named block asynchronously.
