Issue with Razer Thunderbolt 4 Dock on LG Gram 2024 in Qubes 4.3

I’m using an LG Gram 2024 model with Qubes 4.3 and I’m encountering an issue when connecting my Razer Thunderbolt 4 Dock. The dock provides charging, but I can’t get the display or USB mouse/keyboard to work. When I dual-boot into Windows, everything works fine with the dock, so it seems to be a Qubes-specific issue.

Has anyone else experienced this with Thunderbolt devices in Qubes 4.3, or have suggestions for troubleshooting?
