Shut off ^Y.  Capture the ^Y as needed.

Or run the part that can't be bothered away from the user. That can be 
via DECnet task-to-task if you're hacking this stuff—see the xqtype.com 
example on the OpenVMS Freeware—or run the necessarily-undisturbed DCL 
via batch or detached process, or such.

IP networking isn't integrated with OpenVMS, so invoking DCL from DCL 
via sockets is less than easy. DCL and the auxillary server (a.k.a. 
inetd, etc) never got around to directly supporting these cases.
