Set Instant Pot to sauté. When hot, add olive oil and garlic. Cook 1-2 minutes. Add beef and brown on each side.
In a small bowl, add vinegar, hoisin and soy sauces, sesame oil, ginger, and brown sugar. Whisk together and reserve 1/4 cup. Pour remainder of sauce into Instant Pot, covering the beef.
