YES - there are.
Go to the Cemetery Map and set it to search for Portugal. It will open to a view with a lot of blue pins, which are cemeteries without any images. Reduce (zoom out) and those will disappear and you will see several cemeteries in ana around major cities and towns. I clicked on 1 and saw that at least two contributors to that had done so since January 2017.
If you looking for a grave in a particular town or cemetery, you can go to the cemetery already in the BG database, and put in a request for someone to take a photo of a partiuclar grave. You might luck out and have someone respond to a specific request.
