The conflict appears to be between version control and syncing. Is there a possibility that you can disable versioning on the task list you are synching?

Thank JulieS,
But the main purpose is tracking version of this file.
Any time the Project Manager need to change any thing in .mpp file: Task name, start date, finish date, the assignee ...... he have to open .mmp file from Site Assets in SharePoint Site (2-way syncing with MS Project Professional).
So, i want to track version to see who and when modified .mpp file, view the previous version and restore in case of need.
