How to make an object the root of a prefab, or remove the canvas that is set as the root of a prefab

im working in a prefab, and im trying to make a canvas inside of it world space but

render mod isnt an option. Anyone know a fix for this?

I feel this is due to the root canvas that is added to a prefab. I know a canvas doesnt have to be the root of a prefab, but every time i make a prefab it forces one there automatically.
