How do I remove a dashboard lens from the dashboard?

You are able to extend Aero\Admin\Http\Responses\AdminDashboardPage and use the removeLens method. You will need to pass in the key of the lens that you want to remove.

<?php

namespace Acme\MyModule;

use Aero\Admin\Http\Responses\AdminDashboardPage;
use Aero\Admin\Lenses\RevenueLens;
use Aero\Common\Providers\ModuleServiceProvider;

class ServiceProvider extends ModuleServiceProvider
{
   public function setup()
   {
       AdminDashboardPage::extend(function (AdminDashboardPage $page) {
           $page->removeLens('revenue-lens');
       });
   }
}
