Java NIO: Is it possible to "unregister" a SocketChannel from a Selector?

Question

Java

Looking for an "antonym" for SocketChannel.register(selector, SelectionKeys);
Logical question: why should I?
Answer: I want to have multiple selectors in my application. According to the first selector, the server responds to each requesting client with service information. This selector can also be used by the client to combine it with several other clients into a "room" (rooms are processed in separate threads). At the same time, he no longer needs service information, there is no point in pulling the first selector.
Actually, is it possible to do this, what will help me?

docs.oracle.com/javase/7/docs/api/java/nio/channels/spi/AbstractSelector.html#deregister (java.nio.channels.spi.AbstractSelectionKey) - isn't it?
