ASUS Maximus IX Code|no UEFI Bluetooth according to ASUS

Hi,

I read that a few years ago AMI added Bluetooth at the UEFI level for APTIO V based boards so I was trying to get my keyboard (Microsoft Modern keyboard with fingerprint) enabled at boot but it doesn’t work. I asked ASUS support and they said it isn’t available.

Is there a ROM or an update out there that enables the Qualcomm BT on board for keyboard access at boot/UEFI?

thanks!
