Wouldn't that require going back to get an entire BSEE at least?
Anyway, my bigger point is, if you hate focusing in front of the computer, then software engineering is not a career for you and you need to retrain for something else. But, it's very uncertain if you'll like that other thing. So, maybe it's best to just accept the drawbacks of the current career, as other careers might not be better.
Not everything in embedded or robotics is related to Electronics, and many things can be easily understood at a level adequate for development.
