Can't Disable R6 Mark II Noise Reduction

[killacameron]

I've set High ISO speed NR to OFF in my R6II, but it's still applying noise reduction to both straight-out-of-camera JPEGs and RAWs in DPP. The noise reduction is clearly visible on the JPEGs, and when a RAW is opened in DPP the shot settings display non-zero values for both Reduce luminance noise and Reduce chrominance noise.

What am I missing?

SOOC JPEG has luminance NR applied too. You can see it by turning it off completely in DPP and comparing.

There seems to be a base level of noise reduction (both luminance and chrominance) that cannot be disabled in camera, even with all NR settings turned off. Even DPP reflects this with the RAW: with NR turned off in camera, the as-shot reduce luminance and chrominance noise values are 7.6 each. Lower than with NR set to "low" in camera which has them at 8.0, but definitely not 0!
