How can i specify which cpu cores/threads nicehash will use?

Hello! I have a linux server with decent cpu and 16 gigs of ram. Never use it for anything except from hosting game servers. That mostly use core 0 and 1. I know i can specify how many cpu cores to use. But is there any way to specify which cpu cores to use? I would like it to use core 3 to 7 these are my current launch parameters

nheqminer_cpu -l -u wallet.SYS -t 6 Thanks!
