No, not at the moment. You can avoid the prompt by customizing the value
of `gnus-large-newsgroup', but it's still going to retrieve all the
headers for the group.
There's currently no way around this, as Gnus only lets you have one
active Summary buffer at a time, which means all the old data is dumped
every time you switch groups. In the back of my head I have some ideas
for removing this restriction, but it will take a long time to get
there.
