Windows 10 / WMWare Workstation / Nested Virtualisation fails : "Can't use VT-x/EPT" / Disable DeviceGuard - Hyper-V

Notes to myself and to the community :

Can't run Nested Virtualisation on Windows when DeviceGuard is on

WMWare Workstation requires to have access to Intel VT-x and VT-x/EPT for Nested Virtualisation

(The same must be true for other type 2 hypervisors ; Ex: VirtualBox, QEMU, etc ...)

Use case :
