This plugin removes that clickable link — so your logo stays visible but is no longer a hyperlink.
Features:

* Works with <code>the_custom_logo()</code> output 
* CSS and JavaScript fallbacks for full theme compatibility 
* No database modifications 
* Lightweight and fast 
* Works instantly upon activation
