Yeah support is not there yet and it’s unclear if it will be possible right now. See #3243437: Add CodeMirror support for CKEditor 5. I haven’t had time to delve any deeper in to this and probably won’t any time soon so contributions are welcome.

Work is ongoing in #3243437: Add CodeMirror support for CKEditor 5 -- the CKEditor 5 version is now installable in Drupal 10 and I'll update to support Drupal 9 as well once #3238333: Roadmap to CKEditor 5 stable in Drupal 9 lands.
