I looked into this, and unfortunately, it’s not directly possible to cancel document editing in Collabora Online without triggering a save on close. Collabora is designed to save changes to prevent data loss, so even with background_autosave set to false and autosave_duration_secs set to 0, a final save usually occurs when the document is closed.
While there are some advanced workarounds (like modifying the source or specific WOPI server configurations), these are not straightforward or fully reliable for preventing a save action in standard deployments.
