There is no "additional" Intel driver. There is only one (that is
supported) and it is always enabled, never listed in the GUI.

If you have the Nvidia driver installed and would like to try Wayland
(NOT RECOMMENDED) then the steps to use are here:

Title:
  Ubuntu 21.04 not loading correctly intel graphics driver

Status in gdm3 package in Ubuntu:
  Invalid
Status in linux package in Ubuntu:
  Invalid

Bug description:
  I just installed Ubuntu 21.04 and have a problem: I cannot boot into
  Wayland to test it (should be default in 21.04) because, for some
  reason, my system does not correctly work with the graphics drivers. I
  have nvidia+intel graphics on the laptop, but in the Additional
  Drivers tab, I only have the Nvidia one showing. I installed mate-
  optimus to have access to the nvidia settings and be able to change
  graphics from there, that one seems to be working, but Wayland still
  does not show up in the log in screen, maybe because it detected the
  kind of driver and sees it is the nvidia one?

  See the screenshot.

  I have run some terminal commands, but I don't really understand them,
  maybe the outputs helps you (from nvidia drivers the Intel graphics is
  selected):
