You should be able to click on into the "Additional Head Markup" on the blog template and add in HTML for your favicon on that particular template, which should look like this:
<link rel="shortcut icon" type="image/png" href="/link-to-your-favicon.png">
You'll want to change the type if it's not a PNG.
Hopefully that should override the site-wide favicon.
If this helped, please mark it as the solution to your question, thanks!
