Where I сan find information about DebugFlags for minifilter

Hi everyone. I learn this INF file and i can’t find information about this flag. What it means ?
https://github.com/microsoft/Windows-driver-samples/blob/main/filesys/miniFilter/avscan/avscan.inf#L63

I can’t find anything that actually reads or looks at that value. My guess is it’s a copy/paste from some other INF.
