This Microsoft explanation and how to configure the Nested Virtualization: https://docs.microsoft.com/en-us/virtualization/hyper-v-on-windows/user-guide/nested-virtualization
Prerequisites
- The Hyper-V host and guest must both be Windows Server 2016/Windows 10 Anniversary Update or later.
- VM configuration version 8.0 or greater.
- An Intel processor with VT-x and EPT technology -- nesting is currently Intel-only.
- There are some differences with virtual networking for second-level virtual machines. See "Nested Virtual Machine Networking".
You can't run Nested-Virtualization on a Non-Intel Processor according to the above Prerequisites.
But this VMware Website says you can run with AMD processor and shows how to do it: https://communities.vmware.com/t5/Nested-Virtualization-Documents/Running-Nested-VMs/ta-p/2781466
Running Guest Hypervisors with Virtualized HV
Most hypervisors require hardware-assisted virtualization (HV). VMware products require hardware-assisted virtualization for 64-bit guests on Intel hardware. When running as a guest hypervisor, VMware products also require hardware-assisted virtualization for 64-bit guests on AMD hardware. The hardware-assisted virtualization features of the physical CPU are not typically available in a VM, because most hypervisors (from VMware or others) do not virtualize HV. However, Workstation 8, Player 4, Fusion 4, and ESXi 5.0 (or later) offer virtualized HV, so that you can run guest hypervisors which require hardware-assisted virtualization.
With virtualized HV enabled for the outer guest, you should be able to run any guest hypervisor that requires hardware-assisted virtualization. In particular, this means that you will be able to run 64-bit nested guests under VMware guest hypervisors.
Since you didn't post your computer's information except you are using a Ryzen Processor.
