No need to.
Just configure the ports in /etc/sysconfig/nfs and open a hole for them.
E.g:
#
# /etc/sysconfig/nfs
#
# mountd	2050/tcp
# mountd	2050/udp
MOUNTD_PORT=2050

# rquotad	2051/tcp
# rquotad	2051/udp
RQUOTAD_PORT=2051

# nlockmgr	2052/tcp
# nlockmgr	2052/udp
LOCKD_TCPPORT=2052
LOCKD_UDPPORT=2052

# status	2053/tcp
# status	2053/udp
STATD_PORT=2053
STATD_OUTGOING_PORT=2054
