Kernel log

I have a laptop with an Intel AC 9560 card and live in Germany.
My home network uses 160Mhz wide channels, but my laptop only connects using 80Mhz bandwith while other devices uses 160Mhz.

I found out the issue lies in the regulatory information the device uses, because running the command "iw reg get" returns the following:

This shows that while the system is using the correct regulation allowing 160Mhz channels in most cases, the card uses a setting that always prohibits 160Mhz channels.
Since the flag "lar_disable" was removed some time ago and also shouldn't be used, I don't have an official way to fix this, since the device manages itself.
Also this isn't really an issue of lar since it correctly detects that I'm in Germany.
Rather the card itself has wrong or outdated regulatory information associated with Germany (and maybe other regions as well).
