WiFi adapter not found in Ubuntu 20.04 in HP ZBook

Question

This question is similar to 1 and 2 with a minor difference. I have referred to both questions but with no success. Below are the details:

This is a brand new HP ZBook laptop with an Intel i7 processor, and I am trying to install Ubuntu 20.04 on it. There are the following issues with it:

Screen brightness control keys are not working
The WiFi adaptor is not recognized

It was shipped with Windows. So first of all, I updated BIOS and Chipset drivers from Windows OS. Later I deleted the Windows partition and tried installing Ubuntu. The default installation option did not work as the laptop screen seems stuck with the following log:

RP PIO log size 0 is invalid
/dev/nune0n1p2: clean, 197903/62480384 files, 6833111/249919744 blocks

Later, I could install Ubuntu with the "Ubuntu (Safe Graphics)" option. However both the issues mentioned above persist. Below are the system details:
