Not tested yet, but when the default was switched to OVN, ML2/OVS "default"
environment files were updated and should work:
(before that switch, I know
was working fine to do an OVN standalone deployment)

And if the neutron-ovs.yaml/ neutron-ovs-dvr.yaml files do not work out of
the box, they sound worth fixing :)
So you should be able to just add
"-e  /usr/share/openstack-tripleo-heat-templates/environments/services/neutron-ovs.yaml"
to your openstack tripleo deploy command, and get a standalone ML2/OVS env.
