No, not within Pro. You would have to do that in Photoshop. One alternative might be to look through the ESRI Imagery Wayback for another image that has less cars in your area of interest. You can look at this Blog post about the Wayback and there's a link at the very bottom about using it in ArcGIS Pro
Curious . What if you use Photoshop and use the retouching ? I am no expert but I am learning Photoshop and soon to be Illustrator ?
Just curious
