I doubt Ledger would ever admit that they could remove that physical confirmation any time they want, but are you both 100% sure that's how it works?
They certainly wouldn't. I suppose I couldn't prove it without engineering firmware which does exactly that, but have a look at the hardware architecture here: https://developers.ledger.com/docs/embedded-app/bolos-hardware-architecture/https://developers.ledger.com/docs/embedded-app/bolos-hardware-architecture/

The buttons feed in to the MCU, not to the secure element. The MCU is where the firmware is installed. If Ledger can write firmware which says "Perform action x if confirmed by a button press", then I see no reason they can't write firmware which simply says "Perform action x".
