No, the Cabal spec has no support for that. It is assumed that
Setup.hs scripts have minimal dependencies, since the original idea
was that these would be the first user interface, so they must
compile.

My plan is to move away from Setup.hs being the primary user interface
and that would in principle make it possible for Setup.hs scripts to
have other dependencies, however we will need to extend the Cabal
specification and .cabal format to enable it.
