Well manually, no. I can think of two tools that can do it on the fly, SRS and STOPX37, but they also tailor the index extent size, unless it's RRDS. A VSAM file is really two space allocations, one for the DATA portion and one for the INDEX portion.
Alter would only work if the file is unallocated... so I would do a copy, delete, rename process with the correct space allocation.

Hello: Is it possible to alter the secondary space value in a catalog entry for a VSAM file? Secondary space doesn’t show up in ALTER as a valid value to change, so I am wondering if it is possible to just issue a hand-written SVC 26 request to update this field. Effectively I want to give the illusion that a cluster (or data component) has a secondary value when the cluster was originally defined with ‘0’ secondary. Thank you.
