To select the auto-balancer, go to the pools page and to the right of the SUI:USDC pool when you hover over it you will see a blue "+" icon , that is the manual pool. To the right of that is a blue "auto" button, if you hit that you are entering the auto-balancer pool.

There are a few auto-balancers, there is a selection ribbon just above the pool list where you can select to view just those. The SUI:USDC looks the best imo
