Ask a vocal genius how to lower your breath when singing.

Inhale evenly through the nose and mouth, use soft but powerful force, pay attention to the mouth shape and expression, and avoid the airflow touching the microphone. You can consider turning your head appropriately. But I think it is more important to grasp the timing of ventilation, calculate the length of ventilation and adjust the intensity.

I am not an expert, but my personal experience for your reference.
