The TriggerDagRunOperator now has an execution_date parameter to set the execution date of the triggered run. Unfortunately the parameter is not in the template fields. If it will be added to template fields (or if you override the operator and change the template_fields value) it will be possible to use it like this:

my_trigger_task= TriggerDagRunOperator(task_id='my_trigger_task',
                                              trigger_dag_id="triggered_dag_id",
                                              python_callable=conditionally_trigger,
                                              execution_date= '{{execution_date}}',
                                              dag=dag)
