DRV8320: SLx lines strictly necessary?

Part Number:DRV8320

I see the low-side FET source feedback lines are routed from the package to their respective gate driver blocks in the overview diagram. I am wondering if it is strictly necessary to route these pins? I'd ideally like to ground them to reduce complexity in the layout. I'd imagine that the best practice is to route these to as close to SLx as possible, just like routing VDRAIN as close to the high-side drain pins, but in my case it is most likely not possible

Can I ground these directly and still have correct functionality?
