The specifics of your question are not exactly clear but I think you can manage what you want by doing something like:

$request->validate([
   'stringOrFile' => [
        function ($attribute, $value, $fail) {
            if (!is_string($value) && !($value instanceof UploadedFile)) {
                $fail('The '.$attribute.' must either be a string or file.');
            }
        }
 
   ]

]);

Where UploadedFile refers to \Illuminate\Http\UploadedFile and stringOrFile refer to the name of the input your are validating.

However if possible use a different name for the input depending on what it is so you can have more complex validation rules on each different input.
