Is there away to change the read more/less button tag

[noderole]

hi,
is there a way to change this:
<a href="#" data-readmore-toggle="footer__aboutParagraph" aria-controls="footer__aboutParagraph">Read More</a>
to this:
<a href="#" data-readmore-toggle="footer__aboutParagraph" aria-controls="footer__aboutParagraph" class="">Read More</a>
Thank you

You want to add an empty class attribute? Why?
