How to intercept 10086 SMS?

You can try to call 10086 customer service feedback and tell them that you don't need to accept such short messages from 10086.

But it is not recommended that you block or simply refuse. After all, 10086 is the official mobile phone number. If you miss any important information, you will be in trouble. As an operator, there is indeed the problem of "harassing" customers, but there is no better way for the time being.
