Apple say -

Create a bootable installer for macOS - Apple Support

You can use a USB flash drive or other secondary volume as a startup disk from which to install the Mac operating system. These steps are primarily for system administrators and other experienced users.

I say -

GitHub - ninxsoft/Mist: A Mac utility that automatically downloads macOS Firmwares / Installers.
