Yes, I went down the path of an earlier response from this link: URL type variable on catalog form
You create a new variable, type is Macro with Label. The Macro points to the UI Macro in the above link, it's all there.
The only issue I had in the above link was that the link didn't open in a new tab, you just have to add the html code ( target="_blank") to the end of the link in the UI Macro for that part. Here's the variable, the macro is below. Once you use it, you'll see how easy it is.
Here's the UI Macro

<div id="sample_check"> <font>BYOD </font>
<a href="https://www.google.com" target="_blank"><b><font color="Blue">here</font></b></a><font> to surf google.</font>

There are two ways to create variable with a clickable link: 1) Label type by adding a link to annotation; 2) UI Page with a link
