in alot of the asus bios' you can do that, you can set the load amounts and what CCDs you want to take those. But the only thing that its doing that you cant with this method is disabling SMT so I dont know if you get the full benefit from turning that off (I know it helped intel but I havent seen any real difference when I do it on AMD) by just only allowing workloads on the primary thread of each core and making sure you have no processes that can access the other one.
