在 app.json 中设置 `homeButton` ，

{
  "window": {
    "navigationBarBackgroundColor": "@navigationBarBackgroundColor",
    "navigationBarTextStyle": "@navigationBarTextStyle",
    "navigationBarTitleText": "",
    "navigationStyle": "default",
    "homeButton": false,
    "backgroundColor": "@backgroundColor",
    "backgroundTextStyle": "@backgroundTextStyle",
    "backgroundColorTop": "@backgroundColorTop",
    "backgroundColorBottom": "@backgroundColorBottom",
    "visualEffectInBackground": "hidden"
  }
}

界面左上角仍然显示 home 图标。类似地，页面配置中的 `homeButton` 也未生效。
