I need to take the StartDate and enddate returned by my own interface instead of the automatic calculation of the component. I set manuallyScheduled = true, but it does not prohibit the automatic calculation of the component engine

Manually scheduled tasks do not 100% guarantee their start and end stay intact. Such tasks at the moment still respect working time specified in related calendars. So start/end dates are aligned to match working time periods.
We have a feature request for changing such tasks behaviour so they would ignore calendars: https://github.com/bryntum/support/issues/2326
And another feature request that could be interesting to you is: https://github.com/bryntum/support/issues/2327
It's about implementing a static mode in the Engine that would simply returns data as-is w/o any recalculating.
Both of them are not done yet unfortunately. But they are on our plans.
