Hide the page menu from a page

I have a page I'd like to hide the page menu on. However when I go to the page settings the option is not there to hide the page menu. What am I missing?

Wanted to comment that I figured this out. The page I had created was within a dropdown menu. When I moved the page out of the dropdown menu the option became available for me to turn off the page menu for that page. Then the setting stuck when I moved the page back into the dropdown menu.

I'd rather not because then I'd have to go back and adjust the setting on a lot of pages to show the page menu. Anyway per this, I should be able to do this but I don't get the option as noted in the video.

Maybe you can change this.
