CM3 enable GPU acceleration

Hey,
I’m trying to use CM3 for my project, and with default setup everything “works”, but looks like rendering is using CPU and is pretty slow (especially noticable when GStreamer renders video and try to move mouse, it has like less then 5 FPS).
I tried to follow this guide https://docs.radxa.com/en/rock5/rock5t/radxa-os/mali-gpu?Driver=Panfrost%2FPanthor to enable panfrost, but I just get empty string for all “lsmod | grep”.
I also tried to upgrade to Debian Bookworm, I would say that after that desktop environment works a bit more smoothly, but still looks like GPU is not used.

Could you please help me to enable Panfrost for OpenGL?
