session.setMaxInactiveInterval() in Lucee?

My app sets the session timeout to 30 minutes. In a couple of programs, I need to extend this to 4 hours in order to wait for a COM call that may take more than 30 minutes to complete.

In ACF I used the undocumented session.setMaxInactiveInterval(), but this does not appear to work in Lucee.

Is there a way to accomplish this in Lucee and avoid the session terminating before the COM call completes?

Thanks.
