How can I pass User-Agent header with a especial curl parameter -A, not -H?
This code adds User-Agent with -H parameter, not -A:
Http::withHeaders(['User-Agent' => 'Mozilla/5.0 (Android 13; Mobile; rv:109.0) Gecko/111.0 Firefox/111.0'])
This code has no effect:
Http::beforeSending(function(Illuminate\Http\Client\Request $request) {
$request->toPsrRequest()
->withHeader('User-Agent', 'Mozilla/5.0 (Android 13; Mobile; rv:109.0) Gecko/111.0 Firefox/111.0');
});

What about
