Forcing games to run in exclusive fullscreen mode (for nVidia Share/GameStream)

nVidia Share requires games to be run in exclusive fullscreen mode (it cannot be borderless windowed) to be able to work.
Is there a way for me to force games without the option to run in exclusive fullscreen mode?
The game in particular that I'm interested in doing this is Gang Beasts because it has local but no online multiplayer support (nVidia Share solves that problem). It would be great if there were a general solution though because I tried and noticed that quite a few other games I was interested in also did not have the option of exclusive fullscreen mode.

Note: If the game still opens in windowed mode after completing both solutions, locate the full screen option within the games settings/options menu and ensure the box is ticked. The game should now change to full screen mode.Nvidia Shield Gamestream fix streaming issues (Moonlight and Nvidia Shield)
