To summarize up to now and reboot the discussion:
I have installed firmware-git. This is the file that was extracted into /lib/firmware:

The card is not successfully initialized by the stock (6.1.20) kernel:

Granted that I am no expert on this, but I know enough to get myself
into trouble, which is what I proceeded to do. I believe (but could
well be mistaken) that what is needed is a configuration line for that
PCI ID in iwlwifi/pcie/drv.c, something like this one:
IWL_DEV_INFO(0x7F70, 0x1692, iwlax411_2ax_cfg_so_gf4_a0, iwl_ax411_killer_1690i_name),
My attempt was to duplicate then change the new line from 7F70 to 7AF0,
but that was also not successful, with such errors as (clipping because
it's rather long):
[...]
[ 3.960164] iwlwifi 0000:00:14.3: Microcode SW error detected.
Restarting 0x0.
[...]
[ 3.960551] iwlwifi 0000:00:14.3: Starting mac, retry will be

[...]
It does produce an interface but it is unusable.
I assume (but I am definitely out of my depth at this point) that it is
due to the wrong firmware being referenced by that line of code (i.e.
it's a different firmware for 7F70 vs. 7AF0) but I also don't know what
the correct one is, thus I'm asking here. If I'm totally on the wrong
track, I'm fine with that too, I just want to get it working.
Thanks!
