Configure windows 10 that is running a unity game to feel like the computer and OS is a standalone program built just for the arcade game it’s running ( not feel like windows running running a unity game)

I have a unity game running on a mini pc that has windows 10 I want to make it so the computer/windows is basically only for the game ...... so when cpu is turned on it will go into game or at least feel like it’s it’s own special computer made for the unity arcade game !! Not a program running on windows .......... so want to hide folders and make it feel like it’s a standalone game.
