If you prefer not to have the NVMe PIP working, you can simply unplug the 4‑pin header connecting the NVMe PIP to the USB HDMI board, and also disconnect the PCIe FPC ribbon cable.
However, please note that the LEDs on the IO Expander and the RGB fan will likely be brighter than the NVMe PIP.
You can further disable these LEDs:
Turn off the RGB LED on the IO Expander
Run the following command:
sudo pironman5 -re false
Turn off the light on the RGB fan
This requires directly removing the RGB jumper on the fan.
Following these steps should turn off most of the related lighting.
If you need any further assistance, please let me know.
