This doesn't answer your question exactly, but it's a way to achieve something similar for apply.

From man git-config:

 apply.whitespace
       Tells git apply how to handle whitespaces, in the same way
       as the --whitespace option. See git-apply(1).

So open up your ~/.gitconfig or ./.git/config/ and append

[apply]
   whitespace = nowarn

It might also not let you commit something that only changes whitespace, but I'm sure you can overrule that with some flags.
