Disable hyper-threading on a Poweredge R720xd

I was asked to disable hyper-threading on one of our Dell PowerEdge R720XD servers. Looking in the BIOS it doesn’t stand out as an option however it does exist. You simply need to select the logical processor setting and set its value to disable and this will in turn disable hyper-threading, because it will only report one logical process per core.

I hope this helped some of you
