- Run OpenCore Configurator 2.35.0.0 and ensure that it is set to OpenCore 0.6.8 Release Version as shown (from the OpenCore Configurator --> Preferences... dialog):
- Add an entry for SSDT-UIAC-VISION-D-V3.aml to the ACPI section as shown:

However, USB 2.0 protocol is enabled on the front-panel USB-C port.
- USB 2.0 --> HS03
- USB 2.0 --> HS04
- USB 2.0 --> Thunderbolt Port 1
- USB 2.0 --> Thunderbolt Port 2
