I have configured ⌘+space to spotlight, but when its enabled bettertouchtool, this is replace for Siri with the same command, i dont see where can i disable this, anyone know where?
Maybe some more information might help others figure out what you are asking.. Unfortunately what's provided doesn't make much sense.
CMD+Space is Default for Spotlight. Siri doesn't have a shortcut by default, nor is it configured by default in BetterTouchTools.
If you've set it up on your own, it would be under the Magic Keyboard category.
