Yes there is: the "listen" module argument. It's documented at [1],
although using some indirection: the section on
module-native-protocol-tcp refers to module-cli-protocol-tcp for some of
the arguments, and "listen" is one of those not explicitly mentioned in
the section on module-native-protocol-tcp.
