Disabling hyperthreading on EPYC-2

Hello AMD team,
I'm trying to disable hyperthreading in an EPYC-2 machine running on Ubuntu 18.04. I was thinking of adding 'noht' to the "GRUB_CMDLINE_LINUX" line? I know that this was originally developed for other processors so I'm unsure if this syntax is supposed to work for AMD.
Thanks
