You can set the optimization metric that you prefer.

You set the optimization metrics when you train the model. 

PlanIQ automatically employs the best algorithm or combination of algorithms based on the forecast model quality metric. The internal optimization of the algorithm is based on the metric. Such metrics enable you to assess the quality of the model based on its backtest.
This process ensures that the chosen algorithm is best aligned with your business and how you assess forecast accuracy.

If you choose either Anaplan AutoML or Amazon Ensemble, you may want to specify the metric to apply.
