Jack, uhm.. I mean: Check 'pd -help'. Here is the relevant section:

-jack            -- use JACK audio API
-jackname <name> -- a name for your JACK client
-nojackconnect   -- do not automatically connect pd to the JACK graph
-jackconnect     -- automatically connect pd to the JACK graph 


`pd -nojackconnect` should do what you want.

Because I had similar needs, I once created the jackpatch external
available in Deken. It lists JACK clients and creates/deletes
connections between them. Maybe it is useful to your setup.
