You can simply pass some dummy InputStream to WebResourceResponse as shown below.

my_webview.webViewClient = object : WebViewClient() {
    override fun shouldInterceptRequest(view: WebView?, request: WebResourceRequest?): WebResourceResponse? {
        if (request?.url?.toString()?.toLowerCase()?.endsWith("/favicon.ico") == true) {
            val inputStream = "".byteInputStream(Charset.defaultCharset())
            return WebResourceResponse("text", "UTF-8", inputStream)
        } else {
            return super.shouldInterceptRequest(view, request)
        }
    }
}
