This resource pack allows you to disable the environmental fog added in 1.21.6. At the time of making this pack there’s no way to get rid of it within the settings.
This pack keeps other fog types such as the normal render distance fog, nether fog, blindness and darkness effect, inside water/lava/powder snow effect. Making the experience fully vanilla and restoring the game’s look how it was before 1.21.6.

Disclaimer: This resource pack should work in every version from 1.21.6 unless the developers change the coding.
