W10 21H1 install on B550 TW prompts for driver

Greetings.

I recently bought a system with a B550 TW motherboard, RX 6700 XT Challenger 12G GPU and Ryzen 7 3700X CPU. I downloaded the current Windows 10 21H1 ISO from Microsoft and booted to the installer. Unfortunately, the Windows installer complains that it is missing a required driver. The ASRock AAM4D-12 driver DVD does not seem to make the installer happy, as it does not find any suitable drivers for the device in question.

Where can I get the necessary drivers to enable Windows to install from a generic Windows 10 ISO? It's very disconcerting to discover that the ASRock support site makes no mention of the B500 TW anywhere.

Cheers,

P.S. - Shout out to Al for pointing me in the direction of a useful Reddit post that described the exact same problem on a different mobo.

P.P.S. - ASRock, please add the B550 TW to the web site. I've checked on both global and Japan-specific sites and there's literally no mention of it. I don't know whether the board is OEM-only or what, but it's very disconcerting to try to get support for a product that appears to not exist. This is my first ASRock product and the lack of presence of the motherboard anywhere on the site does not give me confidence.
