Have you tried the command WITHOUT 'sudo'?
While I do not know for sure, it is possible that the internet recovery environment is running as 'root' already. But like I said I do not know, and I have not booted into internet recovery to figure it out either.
Of course that also assumes the 'nvram' command exists in the internet recovery environment.MacBook Pro, Mac OS X (10.7.5), 27" iMac, MacBook, MacMini, etc...

I did try that as well. From my limited knowledge of unix commands, I don't believe 'nvram' is in at least the /usr directory and subs. It could be elsewhere but from using /ls in various folders I wasn't able to find it.

Get yourself a small external disk and install a minimal OS X on it for use on occasions such as this one (and you will have more)

If there is no nvram command, it does not matter if there is no sudo or su command.
Frank's suggestion seems to be your best option.
