Is it possible to hide specific options in the Omnibar without disabling them directly?

[XMahoniX]

If the alias in options displays Chinese, an error will be reported, but search engines can use Chinese, so I wonder if I can hide this option in options without disabling it

Below is my code
api.addSearchAlias('百度', '百度搜索', 'https://www.baidu.com/s?wd=');

Since I am new to this, if there is any other way to achieve it, please tell me, thank you.
