Option "Coolbits" is not used - RTX 2070 Max-Q on Manjaro Linux

Hi there.
I’m trying to enable Coolbits so I can change the fan speeds of my Optimus-enabled laptop running Manjaro with an RTX 2070.

My current Xconf is as follows:

cat /etc/X11/xorg.conf.d/10-coolbits.conf 
#
Section "ServerLayout"
        Identifier      "layout"
        Screen 0        "iGPU"
        Option          "AllowNVIDIAGPUScreens"
EndSection

Section "Device"
        Identifier      "iGPU"
        Driver          "modesetting"
        BusID           "PCI:0:2:0"
EndSection

Section "Screen"
        Identifier      "iGPU"
        Device          "iGPU"
EndSection

Section "Device"
        Identifier      "RTX"
        BusID           "PCI:1:0:0"
        Driver          "nvidia"
        VendorName      "NVIDIA"
        BoardName       "NVIDIA Corporation TU106M [GeForce RTX 2070 Mobile] (rev a1)"
        Option          "Coolbits" "12"
EndSection
#

However it is not actually enabled. Using Nvidia bug report, I get the following messages:

cat nvidia-bug-report.log | grep Coolbits
[     7.816] (WW) NVIDIA(G0): Option "Coolbits" is not used
        Option          "Coolbits" "12"
[   114.674] (WW) NVIDIA(G0): Option "Coolbits" is not used

I’m currently at a loss on how I’m supposed to fix this. Any help would be greatly appreciated.
Thanks! <3
