You don't.

What are you trying to solve?

The thing is, by the time pre-receive-hook is run, the packs have already
been transferred to the destination. Otherwise pre-receive-hook cannot do
its primary task of inspecting the history the push is trying to update
the refs with and allow or deny the ref updates.

Presumably you could run "git rev-list --objects" between the values of
refs before and after the proposed updates, sum up their sizes and reject
the push when the push adds too much data for your liking, and the next gc
will clean things up, but if your goal is to cap the maximum disk quota
including the transient use during the time pre-receive-hook is run, it
would not help.
