Alsa/Pulseaudio + Docking Station: Changing hardware addresses

Hi,
I'm using a Lenovo X1 Carbon 7th Gen together with a Thunderbolt 3 Docking Station. My problem is, that Alsa (or PulseAudio?) is setting the Thunderbolt Audio Device as device 0. My internal audio device address now depends on whether my dock is connected during boot up or not and is receiving either 0 or 1 as hardware address.

My current configuration looks like this:

/etc/pulse/default.pa (laptop configuration at the very end, rest should be the default setting)

#!/usr/bin/pulseaudio -nF

Can I maybe define a udev alias, or can I use the name instead of the hardware address in the configuration? But how is the syntax? Otherwise I have to change everytime my configuration, since the internal audio is not detected with the wrong address

Thank you for helping
