Hello,
For more room you can see how high the lights can go, get a bigger tent(but that's not always do-able.
But to the plant, I would try to keep doing as much LST as possible to start it flat before hitting the screen. Then I would do some super cropping, where you'll pinch the tallest branches and slowly weaken their stem and slowly start bending it over, being very careful not to snap it. Being still in veg nows the time to try anything you can if height is a big factor in the grow. I know many people will say to be careful of any high stress methods because it's an autoflower, but your plant looks healthy and can handle a fair bit of stress without any negative effects.
Otherwise you could start weaving through the screen as soon as it will reach and continue to weave the branches in and out and it'll keep things pretty low and even.
Happy growing. ✌️
