How to identify and upgrade my Chuwi

I’ve got a dualboot Chuwi with Android 5.1 and Win10 from a friend and would like to upgrade Android (LineageOS). Model CWI514, HiB Q64G45160504739
Is this really a HiBook and can I use from or is it a HiBook Pro and I’ve to use 5.1 further?
Many thanks

You CWI 514 tablet is a HiBook (no Pro).
