A couple ways that might be available to you, that may get you most of the way to where you want to go.
Click the notification icon lower right most corner of your screen on the taskbar and click to enable "Tablet Mode" IF that is an available option to you.
Otherwise right click any blank are of the desktop and choose "Personalize" select "Start" from the left column and they move the slider to "ON" where it says "Use Start full screen"
See what that produces.
