How to avoid "Component is declared but its value is never read." when I use Vue3 setup syntax?

<template>
  <ConfigProvider :locale="getAntdLocale">
    <AppProvider>
      <RouterView />
    </AppProvider>
  </ConfigProvider>
</template>

<script lang="ts" setup>
  import { ConfigProvider } from 'ant-design-vue';
  import { AppProvider } from '/@/components/Application';
  import { useTitle } from '/@/hooks/web/useTitle';
  import { useLocale } from '/@/locales/useLocale';

  // support Multi-language
  const { getAntdLocale } = useLocale();

  // Listening to page changes and dynamically changing site titles
  useTitle();
</script>

Vetur shows this warning:

'ConfigProvider' is declared but its value is never read.Vetur(6133)

'getAntdLocale' is declared but its value is never read.Vetur(6133)

It seems the template can't read the script with setup syntax variable. How can I avoid this warning?
