Looking for a tablet for taking notes in engineering and deeper math classes.

I always used paper or typing (shoutout notesnook), but I want to have a big digital handwritten journal to look back at and reference.

Or if anyone is familiar with custom ROMs for android and know a good and easy to flash tablet.

I already have a thinkpad x1 carbon laptop for everything else.

Tablet will be separate for reading, home assistant, taking notes with Saber and watching entertainment.

Again, looking for a decently easy Linux tablet or de-googleable tablet with an advanced stylus.

And I'd prefer not supportting Microsoft or Google of course. And budget strictly under $200 l.

Thanks!
