I Stop selling prints

Don’t want to sell prints of my pictures. I hit the button to sell prints accidentally and now all my photos are for sale that I don’t want. How can you change this. Major problems I have like 5000 photos on this site. Can you change it?  What if I decide donee the road I want to sell canvas prints just of my paintings after we fix the sell pictures and can do manually for just certain pictures of my paintings I can sell canvas
