Bootcamp Win10 problems with HDR, keys, and trackpad

I'm on a MBP 16" 2019 with HDR 10.

1. latest Apple/AMD drivers don't enable HDR mode under Windows 10. Is there a monitor profile that Apple can provide/install?
2. trackpad stutters in M2 chip during high cpu usage
3. keyboard keys for VK_OEM3/5/7 are incorrect, mapping to one another

	static bool useBootcampHack = true;
		if ( useBootcampHack )
		{
			if ( button == VK_OEM_3 )
				button = VK_OEM_7; // '" for US
			else if ( button == VK_OEM_5 )
				button = VK_OEM_3; // `~ for US
			else if ( button == VK_OEM_7 ) 
				button = VK_OEM_5; // \| for US
		}
