Does anyone know if it's possible to get Alexa off of it and put custom software on it? Uses I can think of include making it a Bluetooth speaker, putting an open source assistant on it, or any number of other things if I could load custom code.
They document which chips are inside. This is first gen, but they don't have a second-gen with the same chip description. You probably have second (which is for the better, as it's a mediatek running android and much more usable).

I suggest googling for more info. If all else fails, I guess just flashing the nand might do it? In summary, v2 is a linux system which means you could likely run anything linux on it (including an open-source assistant), though I suspect it will take no small amount of hacking.
I'd recommend taking a look at the ifixit teardown here: https://www.ifixit.com/Teardown/Amazon+Echo+Dot+Teardown/613... They document which chips are inside.
