I have an HP laptop with an Realtek 8852BE wifi card, and I am unable to use the driver even though the driver for it is supposed to be included in the kernel after 5.16+ as per lwfinger README.md.
How can I use the driver available in the kernel assuming it is actually available?
Currently I am using this driver, but it is deprecated: https://github.com/HRex39/rtl8852be
I had also tried this driver, but it was unstable: https://github.com/lwfinger/rtw89
Running sudo lshw -C network returns:

Running uname -r returns: 5.19.0-35-generic
I don't know how to see if the driver is available, so I tried to figure out if the module is available using the command below.
Running modprobe -D rtw_8852ae returns:
modprobe: FATAL: Module rtw_8852ae not found in directory /lib/modules/5.19.0-35-generic
Running modprobe -D rtw_core returns:
modprobe: FATAL: Module rtw_core not found in directory /lib/modules/5.19.0-35-generic
Edit:
The HRex39 driver is working at least for now, but since it's deprecated, I wanted to switch to the kernel provided driver. The only annoying thing is that I have to recompile it for every kernel update.
The OS is Ubuntu 22.04.2 LTS
Edit 2:
I have executed the diagnosis script, but I don't see anything that could point me to the cause of the issue. All I see is the iwlwifi being removed, but as far as I know that is only for intel wifi.
Details:
I had unloaded the module with modprobe -rv 8852be which returned:
rmmod 8852be
rmmod cfg80211
Then rebooted... after which it turns out that the driver was loaded again, so I had removed it once more with modprobe -rv 8852be then blacklisted it using: echo "blacklist 8852be" >> /etc/modprobe.d/local-dontload.conf. I rebooted again and this time I no longed had wifi.
I also tried loading both of the following two modules but to no effect: modprobe mac80211 and modprobe cfg80211
Running the script from: https://github.com/UbuntuForums/wireless-info/raw/master/wireless-info returns:

Edit 3: After searching trough the rtw89 commits it looks to me like it is included in the 6.1 kernel. Specifically this merge I would say it adds the 8852BE driver.
- Did I understand correctly in which version it is available?
- Assuming this is true, should I expect the driver to be available when Ubuntu will include the 6.1 kernel?
