I have a similar question. Some people say it's the default, but I have never seen it enabled by default, no matter how recent the hardware or the build number. I wonder under which conditions exactly it is enabled, if any.

If Hyper-V, Windows Defender Application Guard (or a couple other Defender features -- credential guard?) or WSL are enabled, Windows starts running under a hypervisor. By default it shouldn't be, unless your OEM or corporate IT has turned one of those features on.
