SOLUTION

To Configure capture on Active Data Guard if primary is 2 node RAC and DG is non RAC kindly refer below :

From the Active Data Guard(ADG) perspective, when you configure Active Data Guard standby in a single instance database, you should create 2 threads of standby redo logs if the primary database is 2-node RAC.
It will capture both DDL and DML.But please check the limitation on below documentation :
