On a mac that is already running 10.13.4 and that has an APFS drive you can wipe the drive and reinstall the OS without having to boot to anything external, external drive or netboot.

Get the MacOS 10.13.4 (or better) installer from the app store and put it in your /Applications folder. This is were it goes by default if you download it. Then give the following command and sit back:

/Applications/Install\ macOS\ High\ Sierra.app/Contents/Resources/startosinstall --applicationpath /Applications/Install\ macOS\ High\ Sierra.app --eraseinstall --agreetolicense --nointeraction

“–eraseinstall” is new in MacOS 10.13.4 and will ERASE the hard drive before installing the OS again.

“–nointeraction” is undocumented but causes this command to run without human intervention (and therefore can not be interrupted!)

This will but the mac back in the out-of-box shrink wrapped state with an erased drive just like the internet recovery process can do.  Once back to being shrink wrapped, you can, for example, let it run through your JAMF pre-stage enrollment process.
