How can I hide a specific page from appearing in the menu?

I have created a new sub page that I don't want to be shown in the menus. In earlier versions I could set the specific page to not show in menus, but I can't find that option now... Page in question: http://www.ericthoren.se/photo-3/silfra-iceland-2019/ As you can see it appears in the menu PHOTO, but I don't want it to be seen there...
