Thanks for pointing to this. Anway this does not seem to be the relevant
issue. I (being an elisp newbie) learned about M-: and added the value
manually. Now I'm one step further: Using

(add-to-list 'hs-special-modes-alist '(yaml-mode "\\[\\[\\[" "\\]\\]\\]"
"xxxx" nil nil))

I was able to add an appropriate entry to hs-special-modes-alist.

Using this expression, I was able to make hs-minor-mode fold, BUT ONLY
if the brackets are not part of a yaml comment. Which makes me curious!

If I understand the code (line 672 in hideshow.el) correctly,
`hs-c-start-regex` is st ot the 3rd paramater ("xxxx"), which is
documented to be a regex for starting a comment. Thus "xxxx" should
defacto disable comment detection. Yet comments are still considered.

Any hints on this?

The documentation for hs-special-modes-alist is at
<https://git.savannah.gnu.org/cgit/emacs.git/tree/lisp/progmodes/hideshow.el#n268>
and the relevant function `|hs-grok-mode-type`|||at
<https://git.savannah.gnu.org/cgit/emacs.git/tree/lisp/progmodes/hideshow.el#n654>.
