It does. Simply:
cat - <<EOF > /etc/dhcp/dhclient-enter-hooks.d/disablemakeresolvconf
make_resolv_conf() { : ; }
EOF
as is documented in dhclient-script(8):
When it starts, the client script first defines a shell function,
make_resolv_conf , which is later used to create the
/etc/resolv.conf file. To override the default behaviour,
redefine this function in the enter hook script.
