Windows: select or deselect the tasks to show in the calendar.

I tried onetasks - everything works smoothly. The tasks show correctly However there is no option to deselect the tasks. I only need the tasks to show up when I am working on them, not in the general calendar view. There should be a possibility to select the task account like for the calendars Now the only way is to disconnect onetask from the MS365 account or to uninstall onetask ??
