HID compatible Bluetooth adapter

Hi Folks, I‘m running Monterey on my Haswell system with functioning Belkin Bluetooth Dongle. Up until this week I used an apple wired keyboard but want to use a Magic Keyboard. Beside that I’m using a Logitech MX master 3. The Logitech unifying adapter seems to be able to function within UEFI-Bios. I was looking up the internet all day to find a solution for a HID compatible USB dongle. So far I wasn’t lucky. I can’t believe, that Logitech is the only company that is able to build an adapter that is working in BIOS. So my question is, is there any Bluetooth adapter that is able to connect to a device without being in OS?

Thanks in advance. Phillie
