On your default rule you can add a complex filter and exclude device names. if it’s more than 7-8 you may want to make the default logging rule the second rule.
in this case, create a new rule. Have it match on the devices you want and take the action(s) needed. As the last action in the rule add ‘Stop Processing’. This will keep any subsequent rules from seeing the messages. Then your default rule will only see the messages that did not match your first, explicit, rule.
