comment 1 contains the configuration update for vcs-sync modern. However, that only takes effect when the venv is rebuild from scratch.

To deploy, a manual process was used on each virtual env:
  source path/to/vcs_dir/build/venv/bin/activate
  pip install --upgrade mercurial==3.7.3

After ensuring that instance was idle by acquiring the lock file. Roughly:
  cd path/to/vcs_dir
  touch hwine.lock
  while ! ln hwine.lock this_instance_name.lock ; do sleep 10; done
  # when loop exits, you have the lock
  # update per above
  rm this_instance_name.lock
