How to achieve, the length of the parent task is not affected by the child task

How to achieve this, the task and the sub-task exist independently, the parent task will not automatically change with the time of the sub-task.

Usually, parent tasks with the task type do not obtain the start_date and end_date parameters from their children:

It doesn’t work that way if the parent task is loaded without the necessary date parameters (start_date, end_date, duration).
So, if you load tasks with at least 2 of 3 date parameters, the parent tasks won’t obtain dates from their children.

Thank you for your answer. thank you very much.
