Cook the rice as the label directs. Meanwhile, fill a large skillet halfway with water; bring to a boil over medium-high heat. Set the bottom of a stackable bamboo steamer in the water. Sprinkle the scallion whites and 1 teaspoon ginger on a plate that will fit in the steamer basket; set the fish on top and sprinkle with 1/4 teaspoon white pepper. Set in the steamer basket; cover and cook 8 minutes.
Line another steamer level with parchment; add the bok choy and carrots and set on top of the fish basket. Cover and cook until the fish is cooked through and the vegetables are tender, about 7 more minutes.
Meanwhile, heat the vegetable oil in a saucepan over medium heat; add the chile, garlic, the remaining ginger and 1/2 teaspoon salt. Cook, swirling the pan, until the garlic and ginger start browning, 2 minutes.
Remove the baskets. Drain any liquid from the fish; cut into 4 pieces. Drizzle the fish and vegetables with the chile oil and soy sauce; top with the scallion greens and season with white pepper. Serve with the rice.
