I reviewed your post and I understand that the screen flickers when you use the touchpad.
Don’t worry, I assure you I will try my best to get this sorted.
I recommend you update the BIOS and the graphics driver from the below link and check whether the issue is resolved.
BIOS: https://ftp.hp.com/pub/softpaq/sp111001-111500/sp111213.exe
Intel: https://ftp.hp.com/pub/softpaq/sp102001-102500/sp102122.exe
Nvidia: https://ftp.hp.com/pub/softpaq/sp104001-104500/sp104237.exe
Let me know how it goes and you have a great day!
