There is a firmware-2.bin in the QCN9274/hw2.0 folders, but I guess they
are for another chip?
QCN9274 doesn't seem to be present in the current package in the trixie repo,
just WCN7850.

can confirm this works and it seems that the symlink persisted after
installation so the system also had working wifi. > However, I cannot
specify WLAN setting (SSID, password). If I was able to figure out
wpa_supplicant during setup I probably could've gotten it working, but I
opted to not select NTP and just install from the Debian testing DVD1.
