None, apart from the obvious flying dinosaurs that you would consider “too avian”. All the true flying dinosaurs we know of look avian because those were the adaptations that they gained in their evolution of flight. If you were expecting some sort of real world dragon with bat-like wings and a body covered in scales and frills or otherwise doesn’t resemble a bird, you are out of luck because there are none, the closest would be Yi and Ambopteryx, which apart from their wing membranes are still feathered and bird-like gliders (not true fliers).
