IMHO the only thing you could toggle in the kernel config is nfs _server_ over 
tcp (which is enabled in the debian kernels), so the clientside support
should be always available...

good question; this I didn't try yet...

BTW: even nfsroot over tcp works, though isn't documented in the kernels
nfsroot.txt: use something like

nfsroot=server:path,tcp

on the kernel command line to use it.
