+### Granular Chapter Control
+Use `hidden-service-chapters` to selectively hide individual service chapters:
+
+```yaml
+- name: Generate Release Notes
+  with:
+    warnings: true
+    hidden-service-chapters: |
+      Direct Commits ⚠️
+      Others - No Topic ⚠️
+```
+
+Or use comma-separated format:
+```yaml
+    hidden-service-chapters: "Direct Commits ⚠️, Others - No Topic ⚠️"
+```
+
+**Available service chapter titles:**
+- `Closed Issues without Pull Request ⚠️`
+- `Closed Issues without User Defined Labels ⚠️`
+- `Merged PRs without Issue and User Defined Labels ⚠️`
+- `Closed PRs without Issue and User Defined Labels ⚠️`
+- `Merged PRs Linked to 'Not Closed' Issue ⚠️`
+- `Direct Commits ⚠️`
+- `Others - No Topic ⚠️`
+
+**Note:** Title matching is exact and case-sensitive. When `warnings: false`, all service chapters are hidden regardless of the `hidden-service-chapters` setting.
+
