I wonder if the LEDs are a HID device. There are apps that can report the HID info and maybe affect it. USB Prober.app? ControllerMate.app? I'm not sure.I was actually referring to that dock. It's the black version, but they seem to be identical. In a test report it was written that the RGB colours could not be controlled if the dock was used on a Mac because the software does not exist for the Mac. According to the test report, the LEDs would always be switched on. Unfortunately, it is in German: https://www.computerbase.de/2021-05/razer-thunderbolt-4-dock-chroma-test/
All three Thunderbolt ports are Thunderbolt 4 which means any of them can have two displays connected using a Thunderbolt dock. What's unclear is if you can connect 3 or 4 to the left side or if you can connect 4 to just the Thunderbolt ports (not using the HDMI).In addition, I have received interesting information from Caldigit support for people who want to connect 3 monitors. It was not clear, at least to me, that you have to connect the third monitor to the right side of the MacBook.
What's also unclear is if it has 3 extra DisplayPort connections that can only be used by a dual link SST displays so that you can, for example, connect 3 LG UltraFine 5K displays (each display uses two DisplayPort connections of 2560x2880). That would mean that the M1 Max has 6 or 7 DisplayPort connections (#7 for the HDMI port).
An

output for an M1 Max would give some clues.
