+## Disable or control the page data
+
+Using special `documentDriven` meta in your pages, you can disable this feature for specific route or control it's behavior.
+
+### Disable document driven
+
+Setting `documentDriven` to `false` will disable document driven. This means that exposed refs from `useContent()` will be `undefined`.
+
+```html
+<script setup lang="ts">
+definePageMeta({
+  documentDriven: false
+})
+</script>
+```
+
+### Control data
+
+To control document driven data you can pass an object to `documentDriven` meta key and enable/disable specific parts of it.
+
+```html
+<script setup lang="ts">
+definePageMeta({
+  documentDriven: {
+    page: true, // Keep page fetching enabled
+    surround: false // Disable surround fetching
+  }
+})
+</script>
+```
+
+
