NVMe Base Duo, controlling the LEDs

My NVMe Base Duo works fine but the LEDs on each of the NVMe connections are very bright white lights. Is there a way to control these LEDs, either the colour (are they RGB?) or just turn them off. It is stopping me running one of these in my bedroom. I’ve already turned off the Pi’s activity and power lights (by pushing values to /sys/class/leds entries), and the lights on the Ethernet port (with mdio-tool), so this is the last source of sleep-disturbing light.

I don’t think my single base has an LED (at least, it’s not glowing at the moment!)

Hi Team, is there a way to do this?

The status leds on the NVMe Base Duo are extremely bright, they outshine anything else on the RPi, even the activity lights of the Duo itself
