Trigger the saving of a file by a button on my system

I would like to know if it is possible to completely disable the automatic save and the native save button of the ONLYOFFICE editor, so that the saving is controlled exclusively by a “Save” button created in my own application (outside the editor).

In this scenario, which options do I need to disable in the editor configuration, and which event should I use to manually trigger the save from my external application?
