During the automated installation for any OS you have the choice to install using a different path.
** Bulk Deployment of Robots **
This is possible using an XML file for the deployment method. Please see the following documentation:
Bulk Robot Deployment with an XML File - https://docops.ca.com/ca-unified-infrastructure-management/8-5-1/en/installing-ca-uim/deploy-robots/bulk-robot-deployment-with-an-xml-file
***The "installdir" attribute, is where you specify the path to the directory where the robot is installed on the target system. The defaults are: Windows: C:\Program Files\Nimsoft or C:\Program Files (x86)\Nimsoft, and on Unix: /opt/nimsoft However, this can be changed.***
