Can't change process affinity

Is anyone else having issues setting process affinity on the apex process?  I have a Ryzen 1700X CPU and I keep OBS and whatever game I am playing on separate CCX's to minimize cache latency and latency caused by CCX hopping.  I use Process Lasso to automatically set and remember process affinity settings for all my apps and it is not able to change Apex's affinity.  When I try to set it manually in Task Manager it says that I am not able to.
