For commands always use names and aliases from configuration of \Yiisoft\Yii\Console\CommandLoader.
Names and aliases from command class always ignored.

For mark command as hidden start name/aliases definition from |.

Example:

'yiisoft/yii-console' => [
	'commands' => [
		'hello' => Hello::class, // name: 'hello', aliases: [], hidden: false
		'start|run|s|r' => Run::class, // name: 'start', aliases: ['run', 's', 'r'], hidden: false
		'|hack|h' => Run::class, // name: 'hack', aliases: ['h'], hidden: true
	],
],
