I use other mods for shulkerpreview so i want to disable the Tweakeroo shulkerpreview but it isnt possible:( so if you can add a option for that i will be very happy:)

It does have an option: Tweaks -> tweakShulkerBoxDisplay.

Note that MiniHUD also has the exact same feature, do you have it enabled there then if not in Tweakeroo? There it's at Generic -> shulkerBoxPreview.
