How to set 6 physical, 6 hyper threading total 12 cores to hyper-v virtual machine - A parameter cannot be found HwThreadCountPerCore

I have windows server 2012 R2 on physical dedicated server

I have created a virtual machine via Hyper-V and installed Windows server 2019 in it

My dedicated physical server has 12+12 total 24 cores

12 core is physical and 12 core is hyper threading

From dedicated server's hyper-v interface, there is no option to set how many physical cores and how many logical cores for the created virtual machine

So I am trying to set number of threads per core via the command below from powershell (running as administrator) in the dedicated physical server

Set-VMProcessor -VMName aa -HwThreadCountPerCore 2 //aa is the name of hyper v machine

However this command is giving the below error but it should work

What is the error and why it is not working?

How can i set X amount of physical cores and Y amount of logical cores?

    Set-VMProcessor : A parameter cannot be found that matches parameter name 'HwThreadCountPerCore'.

This command has worked on my personal computer which is Windows 10
