Hide a menu from one single page

Hello,

I’d simply like to hide a menu from one page.
I’m using the Oxygen theme and I have 3 menus that appear on all of the pages of my blog (a top menu, a side vertical menu, and a footer menu). I’d like to remove the side vertical menu from one page only. The menu is called (secondary menu in Oxygen).
Pretty simple, but no answer to be found anywhere :0(

Many thanks!

Jeff
