Configuration (Vite+)

import { defineConfig } from "@vizejs/vite-plugin/vite-plus";

export default defineConfig({
  lint: {
    vize: {
      "preset": "incremental",
      "rules": {
        "vue/no-v-for-template-key-on-child": "error"
      }
    },
  },
});

vp run lint

Bad

The child paragraph has the key while the template iteration itself has no key.

<template>
<template v-for="item in items"><p :key="item.id">{{ item.name }}</p></template>
</template>

Good

The key moves to template v-for, identifying the complete repeated fragment.

<template>
<template v-for="item in items" :key="item.id"><p>{{ item.name }}</p></template>
</template>

Good avoids this rule's finding under the configuration above; other rules may still report diagnostics.
