No hope for AX211 wifi working on ubuntu 20.04?

I fresh installed ubuntu 20.04 on my laptop and apt update & upgraded to the latest.

$ uname -r
5.13.0-39-generic

So far BT is working fine but only wifi isn’t working now.
I checked as below

$ lspci -nnk | grep 0280 -A3

Per the answer from here Wireless Network not showing with iwlwifi card

I downloaded backport-iwlwifi-dkms_9340-0ubuntu4_all.deb from https://packages.ubuntu.com/impish/backport-iwlwifi-dkms

and downloaded linux-firmware-20220310.tar.gz from
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/

dkms_9340 install

Installed dkms_9340 as below

$ sudo dpkg -i backport-iwlwifi-dkms_9340-0ubuntu4_all.deb

Copy iwlwifi-so files

And copied all the iwlwifi-so-a0-* files from linux-firmware-20220310

$ sudo cp iwlwifi-so-a0-* /lib/firmware

AFTER REBOOT

After reboot, it looks like the wifi module is claimed but not working

According to this answer ubuntu 20.04 LTS driver intel WI-FI 6E AX211 160MHZ

the AX211 is supported in Kernel 5.14, so unfortunately the support in
even the HWE Kernels for 20.04 LTS are not there

So there is no hope for ubuntu 20.04 to run AX211 wifi module? or just wait for an update for it?
