Anything can help provide that same context switching to a lesser extent. Examples can be wearing your hair a certain way during working hours, or wearing one set of headphones for work and another for play, etc.
Buy a bootable external drive for your computer. Have all your "work" stuff on that drive. When you reach then end of your work day, shut down the computer, disconnect the external drive and store it in a closet until the start of your next work day.
When booted off the work drive, do not mount your internal drive.
