Remove stars from inset box

The inset box on the map that shows the company name has options for getting directions, which is good. However, I have a new client that gets only 4 of 7 stars in Google's reviews, so they don't want the ratings to show on the website-embedded map.

Not trying to remove ratings, just not show them on the embedded map. How can these stars be removed so the map is clean and useful, without the extra information since the iframe code is not visible on the code page?

Hello, unfortunately this is not simple solution. Settings of Google iframe are not so easy accessible.
