+### Pass Additional Arguments
+
+You can pass additional command-line arguments to code-server using the `additional_args` variable. For example, to disable workspace trust:
+
+```tf
+module "code-server" {
+  count           = data.coder_workspace.me.start_count
+  source          = "registry.coder.com/coder/code-server/coder"

+  agent_id        = coder_agent.example.id
+  additional_args = "--disable-workspace-trust"
+}
+```
+
 ### Offline and Use Cached Modes
 
 By default the module looks for code-server at `/tmp/code-server` but this can be changed with `install_prefix`.
