Easy workaround would be to change /lib/udev/rules.d/50-udev-default.rules :
KERNEL=="nvidia*|nvidiactl*", GROUP="video", MODE="0660"
However that requires current user to be in the video group, and that will probably cause a lot of issues on its own, since by default users are not part of the video group, and probably not a change you want to push except in a next major release.
