I'd prefer to use brown basmati rice in this recipe. How should I adjust the amount of water and cooking time?

I love making biryani in the Instant Pot, and usually use brown jasmine or brown bastmati rice instead of white basmati. The only adjustment is with the time. Keep the water the same - always a one-to-one ratio, regardless of the type of rice. Cook on high pressure for 10 minutes and let the pressure release naturally for 10 minutes before opening the lid and proceeding as instructed. ;o)
