Liquid milk/powdered milk conversion in pizza dough?

I'm making school lunch cheese pizza from Max Miller's Tasting History site, but since leaving grade school I became vegan. The recipe calls for milk powder and I could substitute it with oat milk powder, but that's something I'd have to special order and I'm hoping to make this today :) I've read you can substitute milk powder with liquid milk and just reduce the amount of water, but the recipe doesn't call for enough water to entirely do that. Here's the ingredients list: 2 1/2 tsp active dry yeast 1 2/3 cup warm water 2 1/2 cups all-purpose flour 3/4 cup instant nonfat dry milk 2 tbsp sugar 1/4 tsp salt 1 1/2 tsp vegetable oil 1 1/2 tbsp cornmeal According to the conversions I found, 3/4 cup milk powder would equal 3 cups liquid milk so I'm thinking of just substituting all 1 2/3 cups water with liquid oat milk and calling it a day.
