BIG-IQ 8.3 - no BIG IQ Central Management option

Been looking at this some more and wondering if I have found the issue.

The processors definitely support virtualisation as I have checked it using the 'Intel_Processor_Identification_Utility-Legacy' tool for this and that comes up OK if I have Hyper-V disabled - see below:

If I then enable Hyper-V the settings change with both Intel VT and Intel VT-x no longer showing as enabled. 

If I open up Task Manger and look at the CPU details then that does show virtualisation as enabled so it looks as if Hyper-V has taken the role of the Hypervisor and 'disabled' this in BIOS:

That I think is the issue here - the BIG-IQ setup checks for Intel VT-x, can't see that Hyper-V has taken over virtualisation duties and so I don't get the option to build a BIG-IQ. Looking at the requirements listed in the Hyper-V Set up guide would appear to back up my initial thoughts that this could be the problem:

The hypervisor CPU must meet the following requirements :

1. Use a 64-bit architecture.Have support for virtualization (AMD-V or Intel VT-x) enabled.
2. Support a one-to-one thread-to-defined virtual CPU ratio, or (on single-threading architectures) support at least one core per defined virtual CPU.
3. Intel processors must be from the Core (or newer) workstation or server family of CPUs.

Does that make sense or have I disappeared down an enormous rabbit hole of my own making on a sunny day when I could be better off outside enjoying myself? 😆

Assuming I am right then the next question is how do I get around it or am I doomed? 🤔
