If you want to mail order in my country you have to go to a voting place and go through the regular process. Exactly to prevent forced voting. We set these up at libraries and other muniplacity buildings that already offer citizen things (English is my third language sorry). We also have voting busses that go to low voting neighbourshoods and we obviously setup voting in nursing homes, hospitals and such. But the process is always you, alone in the booth, with a piece of paper. Unless you have a physical handicap, then two officials will help you vote. Taking a photo of your ballot is illegal, but as you say, it’s impossibil to enforce. You do have options though, we use pencils in the booth and you can always ask for a replacement ballot until your vote is cast. So you could technically take a photo and still vote another way.
