Crack the eggs into a mixing bowl and whisk until the yolks are broken and everything is well combined.
Spray a saucepan with oil and place it over medium heat. Add the eggs and stir continuously with a silicone spatula until they are fluffy and fully cooked.
Add 1 tablespoon of diced chives during the last minute of cooking. Remove the scrambled eggs from the heat and set aside.
Spray the air fryer basket with oil and place one flour tortilla inside.
Sprinkle most of ½ cup of shredded cheese over the tortilla, leaving about a ½-inch border around the edges.
Spread half of the scrambled eggs over the cheese. Break 3 strips of bacon into small pieces and scatter them over the eggs.
Add a few dashes of hot sauce if desired, then sprinkle with ¼ teaspoon of garlic powder.
Add the remaining cheese from the ½ cup and place another tortilla on top.
Lightly spray the top tortilla with oil. Air fry at 400°F for 4 minutes.
Carefully flip the quesadilla and cook for another 4 minutes, or until both sides are golden and crispy.
Remove from the air fryer and cut into 4 sections.
Repeat the same steps with the remaining ingredients to make the second quesadilla.
