If you’re wondering if you would still be able to plug your phone into your computer to put files on it, let me ask you a related question: Do you think Google would kill the ability to plug your phone in and take pictures and video off of it? I think the answer to that is pretty obvious.

Scrcpy does this. If you delve deep into the options you can even set up keyboard input only, but the default is screen mirroring the tablet to the computer. As to whether or not it works before running your OS I’m not sure, because it works via ADB.
