Cambridge CNX v2 fix volume situation

Hello, I would need to be able to control the volume via Roon remote.
I don’t have the option in the audio setup for DSP volume control.
I read that it is suppose to be a glitch on Cambridge side in the Raat integration, any news on that or any suggestions.
Main system:
External HD
Nuc6i5syh, win 10, Roon core
Cambridge CNX v2
Naim Nait 5si
Kef 107
Remote pc win10 in the study room ( where I would need to control the volume )
Tank you.
