The question is about whether shallow breathing and nose or mouth breathing is better.
Doesn’t matter.
Think simple: One breath moves a few liters of air. Doesn’t fit into one nose or one mouth. It must flow through. You breathe maybe 30 times per minute.
Try to do it “shallow”? Just try it out for a whole minute and watch LOL. No, you need all the air, each minute.
Move all the air through the nose or through the mouth? The virus doesn’t care. The virus can get you through all your membranes.

You breathe 12-20 times per minute, not 30. Average breath is under 0.5 liters, not a few liters.
