Turn off companion screen on Expert Pro 440

@Vivialet I notice in this thread from a year ago you indicated Roon displays the Devialet volume. Mine displays the volume if I use the Roon Ready input, but if I use USB, which I prefer, it doesn't show the current volume, so I do use my phone with the Devialet App. Is there is a setting somewhere that will show that current volume when using USB? In the past I tried the options in Settings (in Roon - Device volume, etc) but that didn't show the volume. Have I missed a setting somewhere else?

Thanks
