The latest update was that FW will get a dedicated team at Insyde.
But we have no idea, if that team is already set up and working.
My personal guess is, that they are currently not working on the 12th gen BIOS, because there are still issues with the FW16 BIOS, which is a priority for FW right now (see Second update on Framework Laptop 16 shipment timing - Framework Laptop 16 - Framework Community )
This is just speculation though…
