"i was told by intel that i have to install and download drivers manually"
Who told you this?
What operating system? Windows 10? What version? 1909?
What is your processor model number?
What is the exact full model number of your laptop?
You can get your dell downloads from, drum roll, dell...

None for Windows 10? That is correct, because dell does not support Windows 10 on your laptop.
If you want Windows 10, all the drivers you need are provided by windows 10.
It is worth mentioning that your processor is not supported on Windows 10.
