aside: false
outline: false

You might be able to look at this method

.vitepress/config.js

transformPageData: (pageData, { siteConfig }) => {
 pageData.params.name = '123123'
  const isEn = /^(en\/)/.test(pageData.relativePath)
  if (/^(en\/)?filter\/*/.test(pageData.relativePath)) {
      pageData.title += `${pageData.title ? '-' : ''}${isEn ? 'Demo' : '示例'}`
      pageData.titleTemplate = 'VitePress'
  }
}

{{ $params.name }}
