A manual summary will generate a summary route and
theres not a way to prevent it unlike in OSPF for
example that I know of. Since you don't want it
advertised, remove the eigrp summary and just create a
static route. If you're trying to do it without a
static then perhaps create the shorter prefix network
on another router and advertise it. That might not be
ideal and might break routing though but a little
policy routing should fix that up.
