Change notehead (notehead set)

Hello, I would like to write notes without a notehead. I have read that it can be done by using the notehead set in engrave mode, but in Dorico 4 this seems to be missing? Can you help out?

You can find the notehead set editor in the Library menu in Dorico 4. If you’re searching the manual, make sure you’re searching the Dorico 4 manual.
