I have a Google Pixel 2, factory unlocked, on stock Android 10, although I could downgrade to 9 if needed. Do the Devs have any preliminary support for this device with which I could help test?

Actually, I have about 30 of them, that someone is asking me to downgrade them all to Android 9 Pie for development purposes. They are all going to be wiped before giving them back, so I could do some minor development of my own.

I am no slouch with Linux, and I know how to compile code, but I'm no programmer, and the thought of doing a "make menuselect" makes me cringe and want to run away. However, if the devs have some theoretical code to try, but no device, I can give it a shot and report back.
