You have to get Shortcuts involved to do this with Notes. Notes does not provide direct integration with third party apps which allow easy, interaction-less creation of notes.
It is easy to call Shortcuts from Drafts, however. If you configure a Shortcut to create a note in Notes for the text input to the shortcut, disabling the “Show Compose Sheet” option, so it does not prompt you - then configure a Drafts action to run that shortcut - you can use it with Select > Operations > Run Action to bulk create notes.
