Page.EnableSessionState equivalent in ASP.NET MVC

Question

With ASP.NET WebForms it is possible to set the session state mode in the page directive:

<%@ Page EnableSessionState="true|false|ReadOnly" %>

Is the same configuration also possible in ASP.NET MVC (e.g. per controller or per action) and if so, how?

(In other words: can I disable or set to read-only session state per controllers/actions? I assume having the session state read/write will result in some overhead, so it might be useful if session state could be turned off if not required.)
