Definitely not an on off switch, it took me ages to get better at turning work off. I think the only advice I can give is to make sure you have non-computer/software hobbies, and practice being more mindful in general. Being mindful lets you get better at noticing when you've got yourself in a work/stress hole again. Thinking about work is involuntary most of the time, you just end up there, but if you can train yourself to notice it you can hopefully get better at stopping it.
