If you mean in ENSL 10.2.x - then there are 2 preconfigured scan tasks - run
#/opt/isec/ens/threatprevention/bin/isecav --listtasks
You will see quick scan (usually Index 1) and full scan (index 2)
To run either of use the index number - e.g. for full scan run
#/opt/isec/ens/threatprevention/bin/isecav --runtask --index 2
To create a custom task refer to the Guide ... there is a section on creating ODS in terminal
It will start with ....
/opt/isec/ens/threatprevention/bin/isecav --addodstask....
The guide lists the other parameters such as namin, scan target and scan config etc.
If the product is ePO managed ODS scan can be configured from ePO ENS Scan configurations.
