Thank you for your additional information. It's the first time I heard that you're not using Windows. Please check whether the following BIOS setting can avoid the behavior you're reporting with OpenBSD:
BIOS Setup -> Config -> Thunderbolt ™ 3 -> Thunderbolt BIOS Assist Mode = Enabled
See the help text. This setting must be Enabled to support Linux and older Win10 versions.
