executing below query on primary db stops log shipping to standby.......i think this is sufficient for disabling your physical standby setup temporary
alter system set log_archive_dest_state_2=defer scope=both;
In future if you want your dataguard setup back..............you can rebuild the standby and enable the log_archive_dest_state_2 parameter.
