    |
    | This configuration option allows you to define the default disk that
    | will be used to store files using the Image, File, and other file
    | related field types. You're welcome to use any configured disk.
    |
     */

    'storage_disk' => env('NOVA_STORAGE_DISK', 's3'),

my filesystems.php config

<?php

return [

    /*

    |
    | Here you may specify the default filesystem disk that should be used
    | by the framework. The "local" disk, as well as a variety of cloud
    | based disks are available to your application. Just store away!
    |
    */

    'default' => env('FILESYSTEM_DISK', 's3'),

    /*
    |--------------------------------------------------------------------------
    | Filesystem Disks
    |--------------------------------------------------------------------------
    |
    | Here you may configure as many filesystem "disks" as you wish, and you
    | may even configure multiple disks of the same driver. Defaults have
    | been set up for each driver as an example of the required values.
    |
    | Supported Drivers: "local", "ftp", "sftp", "s3"
    |
    */

    'disks' => [
        's3' => [
            'driver' => 's3',
            'key' => env('AWS_ACCESS_KEY_ID'),
            'secret' => env('AWS_SECRET_ACCESS_KEY'),

            'use_path_style_endpoint' => env('AWS_USE_PATH_STYLE_ENDPOINT', false),
            'visibility' => 'public',
            'throw' => false
        ],

    ],

    |
    */

    'links' => [
        public_path('storage') => storage_path('app/public'),
    ],

];

my resource fields nova

/**
     * Get the fields displayed by the resource.
     *
     * @param  \Laravel\Nova\Http\Requests\NovaRequest  $request
     * @return array
     */
    public function fields(NovaRequest $request)
    {
        return [
            Fields\Avatar::make('Avatar'),
            Fields\Text::make('Name')->sortable()->rules(['required']),
            Fields\Email::make('Email')->rules(['required', 'email']),
            Fields\Text::make('Phone')->rules(['required']),

            (new Panel('Job Position', $this->jobFields()))->limit(3),
            (new Panel('Employee Information', $this->employeeFields()))->limit(2),
            (new Panel('Payroll Information', $this->payrollFields()))->limit(2),
            (new Panel('Date Information', $this->dateFields())),
            (new Panel('Authentication', $this->authenticationFields())),
