Again, I'm not sure what is considered best practice here, but
something like this should work:

adding this to debian/rules

  export PARAM_PACKAGE_VERSION := $(shell dpkg-parsechangelog -S Version)

and patching setup.py to change

  def get_setup_version(reponame):
      """Use autover to get up to date version."""
      # importing self into setup.py is unorthodox, but param has no
      # required dependencies outside of python
      from param.version import Version
      return Version.setup_version(os.path.dirname(__file__),reponame,archive_commit="$Format:%h$")

to e.g.

  def get_setup_version(reponame):
      """Use autover to get up to date version."""
      if version := os.environ.get("PARAM_PACKAGE_VERSION"):
          return version.split("-", 1)[0]
      # importing self into setup.py is unorthodox, but param has no
      # required dependencies outside of python
      from param.version import Version
      return Version.setup_version(os.path.dirname(__file__),reponame,archive_commit="$Format:%h$")
