This article provides information on changes to the display of USB and Thunderbolt settings on newer BIOS versions.
Newer Dell Notebooks equipped with USB-C or Thunderbolt controllers allows the configuration of those technologies in the BIOS under a single entry. However the layout/display of this was somehow confusing as features which were "not installed" were still visible but greyed out (per the image below).

Following the release of newer BIOS versions, like the example below from the new Precision 5520 with latest BIOS 1.1.3, this changes into separate BIOS entries.

The aim is to improve the display of the installed technology and limit any confusion. Dell will offer BIOS versions for systems with this technology and we recommend maintaining your system with up to date BIOS versions as good practice. Latest versions can be found on the Dell Support site under the Drivers and Downloads section for your system.
