Fry the ground beef and onions together in the metal cooking pot in your Instant Pot using the "saute" function on your Instant Pot until the ground beef is cooked and the onions are translucent. Add in the garlic and fry until brown. Drain the fat.
Stir in the tomatoes, tomato soup, beef broth, bay leaves, thyme, frozen vegetables and pepper.
To cook immediately, press the soup button, seal the Instant Pot, close the vent and cook for 45 minutes. Let it naturally release - you can manually release but for safety's sake I don't recommend it.
Remove the bay leaves. Stir in the cooked macaroni and let it warm up. Ladle into bowls and serve.
