Can you not specify a full list of sections in your exporter code and then
truncate that list to the appropriate value of n before generating the ConTeXt
source from the truncated list?
Assuming you are using an Emacs macro to do the export then the following code
will return the first 2 from the list of section types:
(let ((list '("part" "chapter" "section" "subsection" "subsubsection"
"subsubsubsection" "subsubsubsubsection")))
(butlast list (- (length list) 2)))
I stole that from StackOverflow so I'll leave it to you work out how to get
your depth variable substituted for the 2. :-)
Note that you probably don't want "part" but I include it for completeness.
Best to start with "chapter".
