I assume basically you're trying to announce something to a remote AS but
you don't want them to propagate that AS? If you can't use communities at
all, even standard ones like no-export/local-as then BGP won't do that for
you.
If you actually just want the remote AS to use a direct link for traffic but
the rest of the 'net use another link, AS-path prepending may work - many ISPs
set higher preferences on customer advertisments and will use that in
preference to a peer/exchange point link regardless of AS-path length.

I'm not losing my mind, no I'm not changing my lines,
I'm just learning new things with the passage of time
