To temporarily disable a link in a website that you’re authoring, say the code for the link is:
<a href="URL_goes_here">URL</a>
You can either use css like this:
<a style="pointer-events: none; cursor: default;" href="URL_goes_here">URL</a>
Or use javascript like this:
<a onclick="return false" href="URL_goes_here">URL</a>
