If there is a remote port/address, then there is a connection , i.e. a process is communicating through this port.
You "kill" the port by stopping/deleting the process:
use SHOW DEVICE/FULL BGx:, it will show the process as "Owner process ID".

If there is no 'remote port", then it is a port established by a server listening to this port.
"Killing" the port would mean to stop and/or remove the service.
For port 23 (Telnet) for example it would be:

Many services have shutdown/startup command files in sys$startup:TCPIP$*_SHUTDOWN.COM

Others like most web-servers have their own startup/shutdown commands.
Ports 6000+ e.g. are X11 (DECWindows) transport ports: @decw$shutdown would be the command to "kill" the port.
To remove port usage permanently, remove the services using @UCX$CONFIG or @TCPIP$CONFIG (those which have a service name in the "Service" column of TCPIP SHOW DEVICE).
Others whithout a service name have some startup procedures in the system startup chain.
Ports 102,399 for example are DECnetV (DECnet over IP) ports: they can only be removed by disabling DECnet over IP using net_configure.
