I know the urge all too well...
Bought my bike in July 2020. M2 Course was booked for late October.
I hear stories on RFD and other forums all the time - "got caught driving around my neighbourhood with no plates/insurance". Scared me enough to know it's not worth the risk.
Best solution is to rent a U-Haul trailer for $15, get a buddy with a vehicle that has a hitch, load the bike up, head to a empty parking lot (there were SO many last year) and spend half the day practicing. You can do it every other weekend, once a month, once in a while, etc until you're able to take your safety course. You pay $15 each time to rent a trailer but it sure beats getting caught riding with no plates/insurance.
Note: There are probably people that will not like my advice and believe you shouldn't get on a motorcycle until you've taken the course.
You seem to know the risks involved and have been out riding. Just make sure you're wearing gear.
