In Neil's test:bb task, is it possible to override test-namespaces from the command line?

test:bb {:depends [gen-script]
           :requires ([babashka.neil.test-runner])
           :task (exec 'babashka.neil.test-runner/run-tests)}

I made this throwaway task, but I wonder if there's a better way. Using pr-str feels weird.

test:teodor {:depends [gen-script]
               :requires ([babashka.neil.test-runner])
               :task (babashka.neil.test-runner/run-tests
                      {:nses (pr-str '[babashka.neil.dep-upgrade-test])})}
