Thank you for asking this question in the support community. ADTRAN does not have an "OSPF passive-interface" command, currently. However, if your main goal is to provide OSPF security, then one option would be to enable OSPF authentication on the interface. In addition to providing security, this would also prevent unwanted OSPF adjacencies from being formed with downstream OSPF routers.
Here is a sample configuration:
interface eth 0/2
ip ospf authentication message-digest
ip ospf message-digest-key 1 md5 PASSWORD
