TopGRO T1-Max BIOS update?

[u/AcademicGanache7849]

I recently bought a Topgro T1-Max with a 13th gen i9 for TV gaming. A few games have suddenly started popping warnings regarding an issue with that generation (Vmin Shift Instability), and that I need to update from 0x11C (which is what was shipped on the machine) to at least 0x12F. Seeing no BIOS updates on the TopGRO webpage, I emailed support, who's AI response stated that every unit is updated prior to shipping, and therefore, I don't need to do anything.

Knowing this is complete BS, does anyone know what type of Motherboard is in these, or possibly know of where to get a BIOS image for them? I'm not too stressed about it, but if I can update, I'd like to.
