If you are working for a partner (or HPE), you should have access to DXP Workbench, which allows you to run labs on actual hardware (switches, APs, gateways, ClearPass, etc) that's deployed in a remote lab.
That may be more convenient than using a lab yourself with older hardware and limited resources. Unfortunately this service is only for authorized partners and HPE internal use.
