You can choose not to preload your ball if you want. If nobody on your alliance pre-loads you can go right into cycles at the start of teleop. I will say that if nobody on your team has an auton the chances of loosing the match are much higher as you will probably be behind the whole match and not having an auton is a representation that your partners are probably weaker teams during teleop.

Tldr: you don't need to preload all the bots.
