Only Diplay over thunderbolt 3

I’ve found some general considerations about thunderbolt, to support everything.
I just want to support the display. I there a comprehensive way to do that as a beginner ?

I have an Intel JHL6340 Thunderbolt 3

Here the discussions I’ve found, but they are no sufficient, at least for me.

You can check the settings in your firmware, it probably has some options for configuring the thunderbolt port, but on my laptop it is not possible to only enable the display.

On my laptop, the thunderbolt USB controller is added to sys-usb, I think it’s safe to use.

Keep in mind if you change the thunderbolt settings in the firmware it might change the id of your devices, so you might manually need to assign the correct devices to your sys-usb.
