How to disable 'Set Image as Desktop Background…'

When I right-click an image, the context menu opens with an option to set the image as a desktop background. For almost all web images, this action makes no sense whatsoever, and for the others, I personally never want to use it. How can I drop this action from the image context menu? I have searched settings for context, background, and image, and I have searched about:config for desktop, background, context, etc. Superuser [https://superuser.com/questions/1785212/how-to-remove-set-image-as-desktop-background-and-other-annoying-options-from has an answer] making use of about:config `legacyUserProfileCustomizations`, which I would prefer to evade given its 'legacy' nature. I expected an about:config flag but have not found one.
