Core Isolation

When I open Defender in Windows 20H2, I see Device Security is not checked as though it is not enabled.
I follow along by clicking on it which brings me to core isolation and that shows- "WDCSAM64_prewin8.sys"

I do not know if I am better off not doing anything or trying to fix this issue.
I do not know what that "WDCSAM64_prewin8.sys" means. I think it mentions driver update.

Incidentally, I have two Western Digital external drivers that are disconnected.
Western Digital is mentioned under "WDCSAM64_prewin8.sys.

My question is should I leave Device Security as is unchecked or try to fix it to be enabled with advice as to how?
