Still playing with the Framework 12, now the system is a triple boot, as I installed FydeOS in addition of #popos and #haikuos .
There, tablet mode is working quite well:
* with a virtual keyboard respecting the selected layout in the OS,
* the physical keyboard and touchpad being disabled in tablet mode.
Unfortunately, there is no screen rotation despite the option being active in the settings.
As much as I don’t like chrome, I must admit the system is really nice to use.
