Google coral USB accelerator and Doods

I had DOOS installed in HA installed on raspi4 and all works fine.
recently changed to DOODs2 as well.
recently I got Google coral USB accelerator and plugged into raspi4 USB port.
and changed the config to hwAccel: true.
everything works as before and apparently not observed any improvement.
should i do more configurations? appreciate guidance on this.
