Removing new Roblox fullscreen top bar?

Anything similar to :SetCoreGuiEnabled() for the fullscreen drop menu?
tried doing :SetCOreGuiEnabled() to false for all and didn’t show any results.

My game uses the corners to scroll and has menu buttons at the top of the screen. This dropdown bar is very unintuitive as well as unpleasant for people playing the game. It blocks all my UI and covers the removed top bar area with the “Roblox” which you don’t really need to know because you already know you are playing Roblox anyways and a button for un-fullscreen that takes up 10% of the bar and a X that closes the roblox client.

Looked for solutions through google and here and haven’t seen anything talking about it from what I could find.
