How to export Accessibility in exported PDFs from Illustrator?

[#1]

What are the closest workarounds to create Accessibility in PDFs exported from illustrator?
In order to comply with the wcag 2.1 directive on digital Accessibility, exporting maps etc. from illustrator into an accessible PDF is required. 
I know, I know, Indesign is made for this etc. But I have some cases where that is not an option and I need to find a way around that.

Anyone who knows what to do?
Cheers!

What kind of content is there?

You will need Acrobat to edit the PDF itself.
