https://unix.stackexchange.com/questions/685039/x11-how-to-invert-axis-on-touchscreen-matrix has commands that seem to work (xinput set-prop <id> "Coordinate Transformation Matrix") but the specific values listed there still have the vertical access reversed.

'xinput set-prop "UGTABLET 11.6 inch PenDisplay Pen (0)" "Coordinate Transformation Matrix" 0 1 0 1 0 0 0 0 1' appears to work but only if the tablet is configured as the top display.
