this is continued thread of Ubuntu 20.04 Wifi Option Non-existant (No GNOME, No option in settings).

I followed instructions of Wi-Fi not working on Lenovo ThinkPad E570 (Realtek RTL8821CE) as suggested by response. However, there is still no Wifi connection. It stayed exactly same (I disabled securemode in the BIOS setting)

Thing about my laptop is that it doesn't even have WIFI as a Network option as demonstrated by three screenshots below. Most of others' problems relate to situation where 1) their wifi is too weak 2) Wifi is in questions mark 3) Wifi option is not in GNOME but at least exists in Settings toolbar.

In my case, It's in NOWHERE. Not in GNOME Not in Settings

Edited section : screenshot of rekill command and lspci command rfkill and lspci command

In addition, rfkill does not even list Network Controller but only lists Bluetooth as result (wifi definitely worked in windows) Has anyone seen this issue before?
