It's possible. Done in 4.

Bounce it off the left wall in your first shot and you can land close to the end of the course.

I scored 5. Bank at max power at 5 o’clock from tee, the ball bounces over the wall and skips most of the course.

You can bounce the ball up slightly (presumably the spin from rolling is modeled or approximated, and gives lift when hitting a bumper), which might be enough to skip from the tee to near the end of the course. Not sure that should be considered for "par" though. Took me 14.

edit LocalStorage and you can have whatever score you like

I made it in 3. Git gud.
