Answer 1

If you don't want to create a physical file, I would suggest adding

<link href="data:image/x-icon;base64,iVBORw0KGgoAAAANSUhEUgAAABAAAAAQEAYAAABPYyMiAAAABmJLR0T///////8JWPfcAAAACXBIWXMAAABIAAAASABGyWs+AAAAF0lEQVRIx2NgGAWjYBSMglEwCkbBSAcACBAAAeaR9cIAAAAASUVORK5CYII=" rel="icon" type="image/x-icon" />

in the head section

You can use the minimal data URI.

<link rel="icon" href="data:," />

From https://en.wikipedia.org/wiki/Data_URI_scheme

The minimal data URI is data:,, consisting of the scheme, no media-type, and zero-length data.
