According to this documentation: https://learn.microsoft.com/en-us/azure/data-factory/tumbling-window-trigger-dependency#monitor-dependencies
In Azure Data Factory (ADF), the timeout period for a tumbling window trigger to wait on dependency triggers is currently not configurable. By default, a tumbling window trigger will wait for up to 7 days for all its dependencies (including other triggers or pipelines) to complete successfully. If the dependencies do not succeed within 7 days, the trigger fails and the window run is marked as failed.
