You can use pgoptions to set the configuration parameter.
Connect to the master in utility mode to do catalog maintenance. For example:

Uploading Configuration File Changes Only
The gpstop utility can upload changes to the pg_hba.conf configuration file and to runtime parameters in the master postgresql.conf file without service interruption.
Active sessions pick up changes when they reconnect to the database.
Many server configuration parameters require a full system restart (gpstop -r) to activate. For information about server configuration parameters, see the Greenplum Database Reference Guide.
To upload runtime configuration file changes without restarting
$ gpstop -u
