Leave pork at room temperature for 30 minutes prior to cooking and sprinkle with salt. Preheat oven to 350 degrees.
Combine avocado oil, garlic, rosemary, orange zest, and white wine together.
Place the pork on the rack in a roasting pan, and rub the marinade mixture all around it, letting it drip into the pan. Also place a 1/4 cup water in the bottom of the pan.
Bake for approximately 1 hour until the pork measures 145-150 degrees with a meat thermometer. Remove from oven and tent with foil for 10-15 minutes.
Slice and pour the drippings from the pan over the pork. Serve immediately.
