Consider using REJECT. This has two advantages: it gives the end
systems you are now blocking a chance at state cleanup (instead of
needlessly wasting memory and CPU resources on a connection that you
now elect to forbit). But, the greater advantage: the packets that
the end systems exchange in response to the connection teardown,
are JUST what you need to get rid of their conntracks.

Of course, one could do what you requested. Maybe even without coding.
I wouldn't know. Maybe others.
