As you old module depends on something that is no longer reliable there, you should look at other ways to solve this, I think Jon posted a good suggestion about changing the regex rules in the SEO settings of your site
TabSettings are key-value pairs so there is no such thing as a missing setting. A record is set somewhere in code, probably on tab save.
In which version of DNN did you see a UI element to change the value of this property?
I've checked some DNN versions for this and could not find that it ever was a setting which was available in the UI. But it sure is a setting which is available in the (DNN core) code. And for me (at least in this case) it has a function. And since it is available in the DNN core code it must have (or must have had) some kind of a function. So why not make it available for others to use? You can check here for example: https://github.com/dnnsof...UrlRewriter.cs#L1951
