I could set FilterPolicy using set_subscription_attributes.
DeliveryPolicy and RawMessageDelivery were valid attribute names in the description of this page, and FilterPolicy could be used too.

我可以使用set_subscription_attributes设置FilterPolicy。 DeliveryPolicy和RawMessageDelivery是此页面描述中的有效属性名称,也可以使用FilterPolicy。

https://docs.aws.amazon.com/sdkforruby/api/Aws/SNS/Client.html#set_subscription_attributes-instance_method

params = {subscription_arn: subscription_arn, attribute_name: 'FilterPolicy', attribute_value: '{"event_type": ["order_placed", "order_cancelled"]}'}
client.set_subscription_attributes(params)
