from the man page, this seems to do what you want
(never tried, i use dhclient and its /etc/dhcp/dhclient.conf):
-C, --nohook script
Don't run this hook script. Matches full name, or prefixed with 2
numbers optionally ending with .sh.
So to stop dhcpcd from touching your DNS or MTU settings you would
do:-
dhcpcd -C resolv.conf -C mtu eth0
yoyo
