Dell Optiplex 9010 USFF - PCI Simple Communications Controller

I just did a fresh install of the OS an I wanted to know if I should install the following drivers:

- PCI Simple Communications Controller
- PCI Serial Port

I know it installs AMT but I don't use it because I'm a home user. If I just disable them, will they really be disabled? Will it cause problems on my pc? If yes, what would those problems be?
