Because it’s so short and stout - I don’t think bending the whole stem would work well without clearing out some lower stuff, but not a good idea with an auto.
I would try and tie some of those lower long branches down horizontally.
Or wait a week or so for the stretch and you’ll have more to work with.
It’s rarely too late for LST, not until usually week or 3 or 4 of flower is it getting too late
