如何忽略Laravel Nova中数据库操作中的字段

<?php

namespace App\Nova;

use Illuminate\Http\Request;
use Laravel\Nova\Fields\ID;
use Laravel\Nova\Fields\Text;
use Laravel\Nova\Fields\Number;
use Laravel\Nova\Resource;

class User extends Resource
{
    /**
     * The model the resource corresponds to.
     *
     * @var string
     */
    public static $model = 'App\Models\User';

    /**
     * Get the fields displayed by the resource.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return array
     */
    public function fields(Request $request)
    {
        return [
            ID::make()->sortable(),
            Text::make('Name'),
            Number::make('Age'),
            // 注释掉以下字段代码，忽略它们
            // Text::make('Email'),
            // Text::make('Phone'),
        ];
    }
}
