When creating a new Virtual Machine, the option Enable Windows Virtualization Based Security (VBS) is unchecked by default. Currently, the system does not allow administrators to modify the global default behavior to have this option pre-selected.
The default state of the Enable Windows Virtualization Based Security option is predefined within the virtual machine creation workflow. vCenter Server does not provide a global configuration parameter or policy setting to modify this default selection state.
Since the default selection state cannot be changed, it is suggested to create a VM Template with VBS already enabled:
Enable Windows Virtualization Based Security.Convert to Template.Deploy VM from Template and choose the template with VBS enabled.
