Lifecycle manager and HPE servers

I was read Lifecycle manager document as I understood with t we can do follow tasks :

1 - updae esxi

2- update vcsa

3- if using HPE server can via SPP can update firmware and all drivers on server

Is that correct or can do other things ?

4 - As I understood we had to just use ILO Ampifier and integrate it with vcsa is that correct or in adition had to deploy oneview for lifecycle manager ?
