It could also be that it isn't so much the tech job but rather an office job that's bugging you so much? There are worlds of difference in lifestyle even with the same job title. For instance my last and my current gig:
Sr. network engineer-Consulting company-General kinda work:
Wake up whenever, answer mail from home, go mountain biking, come back and remotely attend meeting, drink beer, do design, book flight, hotel and car for next week's on site. Catch uber to airport, fly to somewhere else, get a rental car, go shopping. Wake up and meet customer, get to work, install technology, eat lunch with customer, more work, make it work with no politics involved, get signoff that everyone is happy, explore town, drink beer, fly back home. The 'boss' doesn't really direct my activities, just assigns the project and it's all me from there.
Sr. network engineer-Big Tech-General kinda work:
Wake up around 5am, ride bike in the work by 5:30-6am. Shower, yoga, meditate. Read e-mails, respond. Test upcoming change in lab, make procedure doc. Go for a walk. Meet to get approval to do some minor change. Lunch. Meeting to listen to people get approval for their minor changes (do work during this), another walk, send e-mails. Bike back home and do family stuff. 8pm make change after production hours, verify nothing broke, call it a day, drink beer.
I loved job A, it was challenging but had free travel, and I was basically being my own boss even as a W2. I'm back in an office now for family stability and like you I can't say it's that much fun for me. But I weave in as much stuff that I do like to keep me going. And it'll get me FI quicker as well, so hard to complain too much! Maybe think about a different job style within your current career before you decide to chuck it all and become a park ranger. :D
