coreinfo -v only reports CPU capabilties, not if it is enabled in the BIOS

The IsProcesserFeatureEnabled SysInfo API gives us that information if given the right encouragement! Namely, PF_VIRT_FIRMWARE_ENABLED...

Requires Mingw64

$ gcc main.c -o main.exe
$ main.exe
VTX Enabled: false

Simples!

This is much harder than it needs to be! According to the Golang wiki there are numerous ways to do this. I've created main1.go, main2.go, main3.go as examples. None of them work.

main1.go causes a panic! YAY!

main2.go and main3.go return the error Incorrect Function

Good old main.go is the only way to make this work so far, and it requires Cgo :(
