Hi:
See if installing this W11 Intel Serial I/O driver and restarting the PC installs those devices...
30.100.2129.8 Oct 14, 2021
This package contains the driver that enables the Intel Serial IO Drivers to be used with supported models that are running a supported operating system. Intel Serial IO Bus Drivers software stack provides drivers for these IO modules to control the serial interfaces and sensors that are connected in the Intel Serial IO buses.

Here is a partial copy and paste of the driver setup information file which shows driver support for the two devices that have issues.
