This datapack will disable Curios/Trinkets/Accessories support and remove the calendar slot for SeasonHUD and SeasonHUD (Fabric) starting with version 1.9.7.
Add the datapack .zip to the ".minecraft\saves\WORLD_NAME\datapacks" folder. Once ingame you can use the "/datapack list" to ensure it is enabled.
You can also use a mod like Global Packs and then add the datapack to the ".minecraft\resourcepacks" folder.
