can you (theoretically) run only NFSv4 (without earlier versions)?

how does one configure fedora 20 to support only NFSv4? i'm used to
mucking with /etc/sysconfig/nfs in earlier versions of RH, and tweaking
the variables MOUNTD_NFS_V* and RPCNFSDARGS. i don't see those vars
in fedora 20 and, according to "rpcinfo -p", i'm currently supporting
NFS versions both 3 and 4. so how does one turn off NFSv3? thanks.
