If you want to do the bare minimum, a good starting point would be removing any work accounts from your phone. Make an effort to close your work laptop at the end of the work day. Focus on your main goals during the day, perhaps some project you want to finish before it ends. All this will allow you to focus on either what's expected of you, or what's truly important to you.

That said, I do agree with the other comments here suggesting a talk with the manager or a new job. Why get yourself stuck in a situation where you can't take pride of your work?
