Can't start VM with VT-x enabled on Workstation 16 when Hyper-V is enabled

[purplecandy]

Every time I run my VM with VT-x and Hyper enabled I get this error, "Virtualized Intel VT-x/EPT is not supported on this platform." then it asks to continue with disabling VT-x.

This is very strange because now VMWare 16 now has support to work alongside Hyper-V but I'm not able to run any of my machines with VT-x enabled along with Hyper-V. I tried to do a complete clean re-install and tried with new VMs but still no luck.

My configurations:

Windows 10 Pro, 64-bit (Build 19041.329) 10.0.19041 (Version 2004)
VMWare 16.0.0 build-16894299

It looks like you can have cake but won't be able to eat it.

Starting with 15.5.x, a User Level Monitor (ULM) is used instead of the root VMM.

If Hyper-V is uninstalled from the Windows host, the root VMM will be used and nested virtualisation will be back to the way it was in previous versions with the root VMM.
