Installing MacOS Big sur one a Dell Latitude E5440

Hello, I wanna install Big Sur on my Dell laptop, but I couldn't find where or how to start. And I've got some questions also

  1. Will I keep all the functionality of my computer? such as wifi, Bluetooth and so forth
  2. How the performance will go ?
  3. What are some pros and cons of doing that ?
  4. Will I get updates normally & can use everything ?

With that said, my specs are this:

Intel i7 vPro 5th Generation ( I think ) 8gb ram DDR3 500GB HDD [I'm planning to do it in a 160GB HDD] Intel HD Grapics 4000 + Nvidia GT 720m

and BTW, if I do something wrong can I mess up my whole laptop?
