Yes, "non-free-firmware" is enabled, and there are plenty of intel packages
installed and modules loaded, but I'm not sure which is helpful to this:
$ dpkg --list | grep intel
ii firmware-intel-graphics 20250410-2 all
Binary firmware for Intel iGPUs and IPUs
ii firmware-intel-misc 20250410-2 all
Binary firmware for miscellaneous Intel devices and chips
ii intel-microcode 3.20251111.1~deb13u1 amd64
Processor microcode firmware for Intel CPUs
