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.
