You can pass the crossorigin attribute to the img in Avatar without this change:

<Avatar
  alt="Remy Sharp"
  src="https://next.material-ui.com/static/images/avatar/1.jpg"
  imgProps={{ crossOrigin: 'anonymous' }}
/>

I've tried that, too. But in Edge 91.0.864.59, it just failed to load.

And report has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

@eps1lon Maybe referrerPolicy is also needed by users.
