+^^^^^^^^^^^^^^^^^^^^^^^^
+The hardware type ``irmc`` and iRMC classic drivers support secure boot deploy.
+
+.. warning::
+     Secure boot feature is not supported with ``pxe`` boot interface.
+
+The UEFI secure boot can be configured by adding ``secure_boot`` parameter,
+which is a boolean value. Enabling the secure boot is different when
+Bare Metal service is used with Compute service or without Compute service. The
+following sections describes both methods:
+
+* Enabling secure boot with Compute service:
+  To enable secure boot we need to set a capability on the bare metal node
+  and the bare metal flavor, for example::
+
+    openstack baremetal node set <node-uuid> --property capabilities='secure_boot:true'
+    openstack flavor set FLAVOR-NAME --property capabilities:secure_boot="true"
+
+* Enabling secure boot without Compute service:
+  Since adding capabilities to the node's properties is only used by the nova
+  scheduler to perform more advanced scheduling of instances, we need
+  to enable secure boot without nova, for example::
+
+    openstack baremetal node set <node-uuid> --instance-info capabilities='{"secure_boot": "true"}'
