Hi,
As per below article, I think Windows 10 IoT core might not support Hyper-V feature.
https://learn.microsoft.com/en-us/virtualization/hyper-v-on-windows/reference/hyper-v-requirements
Operating System Requirements
The Hyper-V role can be enabled on these versions of Windows 10:
Windows 10 Enterprise
Windows 10 Pro
Windows 10 Education
But you can read the article and follow the guidance to check if you can run Hyper-V on your device. And if you can enable Hyper-V, I also found below threads about creating a Windows IoT Core Virtual Machine for your reference.

Hope above information can help you.
Thanks,
