Is there any built in feature that allows the server to rate limit the write request? For example, if the client is reading some coils every second and writing exactly the same data too frequently (data has not changed) to some OPC-UA Server Variables, is it possible the server limits that writing frequency or is it something that the client by itself needs to implement?

There is no direct way to limit the accepted write request frequency. Maybe you can describe your use case in more details. So you have a client that is reading data from somewhere and is writing that data to a OPC-UA server? Are you developing the client, the server or both? And what is the problem of changing a value in the server every second?
