You could get him something like this. Using a playpen zip tied to his crate will allow him more space so he isn't cooped up as much. My boy never tried to jump over the car or playpen but if yours would take that into consideration! I actually think the playpen helped transition my boy to having freedom. He's been able to free roam since about 7-8 months with the exception of a gate that my cats can get through blocking off the hallway to the bedrooms. I also set up a ring camera when I leave and the second he would start getting into something I told him no through the camera. That seemed to help! Otherwise I would incorporate daycare if I was you at least 2/3 days you aren't home. He will have time to chill out but right now he's a pup and he should be able to exert energy if possible!
