Preheat the oven to 400°F (200°C) and line a baking sheet with parchment paper.

In a mixing bowl, whisk together the whole wheat flour, baking powder, salt, garlic powder, and onion powder.

In another bowl, mix the Greek yogurt, eggs, and milk until well combined.

Gradually add the wet ingredients to the dry ingredients, stirring until just combined.

Fold in the shredded cheese, crumbled bacon, and chopped chives.

Turn the dough out onto a floured surface and gently knead it a few times until it comes together.

Pat the dough into a circle about 1 inch thick and cut into wedges or use a biscuit cutter.

Place the scones on the prepared baking sheet and bake for 15-20 minutes, or until golden brown.

Let cool slightly before serving.
