Intel NUC10i7FNK : Wi-Fi 6 AX201 sur une Red Hat 8.1

Premier constat après l'installation de Red Hat Enterprise Linux 8.1 sur un Intel NUC10i7FNK, ni l'interface ethernet ni l'interface WiFi ne sont reconnues. Je décide d'installer le driver de cette dernière en premier :

# dmidecode -t 10
On Board Device 6 Information
        Type: Other
        Status: Enabled
        Description: Intel(R) Wi-Fi 6 AX201

# lspci -nnk | grep -A3 "Network"
00:14.3 Network controller [0280]: Intel Corporation Device [8086:02f0]
    Subsystem: Intel Corporation Device [8086:0074]
        Kernel driver in use: iwlwifi
    Kernel modules: iwlwifi

En consultant les traces du système, j'obtiens les dernières informations manquantes :

# journalctl -k -o cat | grep iwlwifi -C5

iwlwifi 0000:00:14.3: check git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git

Après une rapide recherche, je trouve la page dédiée aux drivers Intel pour Linux avec le driver associé à la carte AX201 :

Intel® Wi-Fi 6 AX201 160MHz iwlwifi-Qu-48.13675109.0.tgz

Je copie le fichier iwlwifi-Qu-b0-hr-b0-48.ucode dans le répertoire /lib/firmware comme indiqué dans le fichier README.iwlwifi-Qu.ucode présent dans l'archive du driver.

Un reboot plus tard (ne sachant pas encore comment chargé directement), le driver est bien vu mais ne fonctionne pas :
