Sift 1 1/2 cups all-purpose flour, 1/3 cup granulated sugar, 1 1/4 teaspoons baking powder, 1/4 teaspoon baking soda, and 1/8 teaspoon kosher salt in a medium mixing bowl.
Cut cold 6 tablespoons butter into small chunks (½ tablespoon-size pieces) and add to the dry ingredients.
Use a pastry blender or two forks to cut the butter into the flour mixture until the butter is broken down into pea-size pieces.
Add 1/2 cup buttermilk and stir to combine into a rough mixture.
Add the 1/2 cup strawberries into the scone mixture and gently stir to distribute the strawberries evenly without squishing them.
Form the dough into a circle and pat out until it is only ¾” thick.
Score the dough lightly into wedges and lift carefully into the greased basket of the air fryer. (A greased air fryer basket is preferable to using parchment paper - see note below).
Set air fryer temperature to 350 degrees F and set cook time for 12-15 minutes or until the scone is cooked all the way through.
Whisk together 1/4 cup powdered sugar and 1-2 tablespoons heavy whipping cream, adjusting the amount of cream until desired consistency is reached.
Drizzle glaze over scones and allow to set.
