Where does HLK search for driver installation files?

Reza Ahani 1 Reputation point

In "DF - Reinstall with IO Before and After (Reliability)" test, HLK reinstalls the driver multiple times. The question is where do I have to put my driver installation files to be accessible for HLK?
I copied them to this address on Windows 11 client, and didn't word:
C:\Program Files\Windows Kits\10\Testing\Tests\Additional Test directory
