Problem with hitting my head on Mare's Hybrid BCD

[DukeAMO]

So, I was looking at a video of this BCD. It looks like the handle is rigid and attached to the back assembly. The BCD probably needs to be positioned so that the lumbar support and hip belt are in the right place on your body, and that's making the handle come up too high. Is there any way to move the lumbar support and hip belt up so there's less space between them and the handle?
