Optimization possible for Vray 6 (on a laptop)


I am student and this year for one my course we’ll be rendering with vray in rhino. I was wondering if there some options or tricks or some data/inputs I could change to let’s fine tune Vray for my laptop. For example the bucket size and other stuff.
I am always rendering from CPU ( amd R9 5900HX) as I believe an rtx 3070 mobile isn’t really going to cut it. Also got 32gb ram.

Thank you
