/System/Library/CoreServices/Applications/System\ Image\ Utility.app/Contents/MacOS/imagetool

The network volume must contain a version and build of macOS that is compatible with the Mac using it. To prevent a Mac from trying to start up from an incompatible network volume, use the Filter Computer Models workflow action with System Image Utility.
