OPC HDA Subscribe to data change|Classic OPC: DA, A&E, HDA, XML-DA, etc.|Forum|OPC Foundation

Can I subscribe to data changes from the HDA server in my HDA client? For example if I want to automatically get new data from the start timestamp to the present. I use C# and OpcNetApi.dll. By analogy in DA I can create subscription and subscribe to DataChanged event or create monitored item in UA with UA-.NETStandard libs.In the HDA specification, I found only such words in the section of asynchronous interfaces:
“It can ‘subscribe’ to data using the Async methods, which is more complex but very efficient. This is the recommended behavior for interactive clients because it will minimize display lockups. The client would be free to process other interactions while waiting for the data to return”
