Share a notebook publicly by using the publishing feature in old Evernote legacy version:
Download the Evernote legacy version, sign in, install and sync it.
Legacy download info: https://help.evernote.com/hc/en-us/articles/360052560314-Install-an-older-version-of-Evernote
Follow these old instructions from Evernote "help":

Unfortunately, the Shared Published Notebook link only renders correctly in Firefox (It doesn't render correctly in MS Edge or Chrome).
Best!
