The other option is a Y adaptor that you plug into 2 120v outlets that are on opposite phases. You could buy that or make one:

Sadly there are no open circuits in the panel. I would need to install wafer breakers to open up any slots, and in order to open up enough slots for enough amperage for 240 charging, I'd have to install a LOT of wafer breakers. Again, since this is a rental, I'm not going to do it myself, and it would be $$$$$ for a licensed electrician.

It's substantially more efficient going from any 120v to any 240v amperage.
I modded my 120v Panasonic brick evse to run 240v, it was real easy.

Out of curiosity, what makes it more efficient? I'm assuming there's some loss of power through heating and when you do 240V you move so much more electricity that relative to the current you draw the waste is lower?
