No need to change the ebuild; just put your patch (filename must end
in .patch) in

/etc/portage/patches/x11-drivers/nivida-drivers/

nvidia-drivers uses epatch_user; from the docs of the eclass:

# User patches are intended for quick testing of patches without ebuild
# modifications, as well as for permanent customizations a user might
# desire. Obviously, there can be no official support for arbitrarily
# patched ebuilds. So whenever a build log in a bug report mentions that
# user patches were applied, the user should be asked to reproduce the
# problem without these.

Regards.
