The Moon subtends only about a half degree of arc, and the camera's field of view on your drone subtends eighty-eight degrees. So, the Moon is only 176th the width of the image frame. Since the image frame is only 5472 pixels wide, an image of the Moon would be only about 31 pixels wide. What kind of detail would you realistically expect to capture of a subject that's comprised of so few pixels? The photos which accompany your original post tell the tale. The Moon appears as just a tiny speck in the sky.
If I were you, I'd shoot for the most pleasing overall scene exposure and not worry about detail on the Moon.
