+## Managing Interface Exclusions in Netifyd

+```
+uci add_list netifyd.@netifyd[0].exclude='eth1'
+uci add_list netifyd.@netifyd[0].exclude='tun'
+uci add_list netifyd.@netifyd[0].exclude='wg'
+uci commit netifyd
+```
+
+- Modify Exclusion List
+```
+uci delete netifyd.@netifyd[0].exclude='eth1'
+uci add_list netifyd.@netifyd[0].exclude='eth2'
+uci commit netifyd
+```
