Download the all-new Radeon Software Adrenalin 2020 Edition 20.12.2. This release support only the Radeon 6800 (XT) and 6900 XT.... AMD Radeon Adrenalin Edition 20.12.2 driver download
I thought 6800 (XT) had meant both RX 6800 and RX 6800 XT. Otherwise, why bracket the 'XT' part for the 6800?
Yeah apparently there's no RGB LED on the 6800 for the AMD logo on the card so the driver doesn't apply to this model. EDIT: Should have compared if they included newer versions of the Radeon Settings software and such, likely there's no real change here from 20.12.1 other than this function now being ready for the 6800XT and 6900XT GPU's at last but could have some newer bundled software or such. (Doubt it, probably just finalizing the RGB support that wasn't ready in time for the 6800XT GPU launch.)
