Yes.

See *print-length*, *print-level*, and *print-lines*.

In your case, I think you want *print-length*

Acording to Paul Graham (p. 395):

"*print-length*

Either nil (the initial value) or a positive integer. If an integer, up to
that many elements of an object will be displayed, the rest being elided.
If nil, there is no limit."

So try

(setf *print-length* 10) or 20, or whatever...
