SMUDebugTool has now migrated away from WinRing0 to PawnIO, meaning you can use it to set the Curve Optimizer values from within Windows without having to set an exclusion in Windows Defender for the old WinRing0 system driver (which is now being detected as malicious by the Windows Defender).

I'm currently looking for a way to migrate CoreCycler to PawnIO as well (as it's using ZenStates-Cores for that as well, just like SMUDebugTool), so that it doesn't trigger Windows Defender anymore as well, but I have no exact ETA for this yet.
