Rule 112.11
Official source text from the 25 January 2019 Rules release
Effects can stop an object from having a specified ability. These effects say that the object "can't have" that ability. If the object has that ability, it loses it. It's also impossible for an effect to add that ability to the object. If a resolving spell or ability creates a continuous effect that would add the specified ability to such an object, that part of that continuous effect does not apply; however, other parts of that continuous effect will still apply, and that resolving spell or ability can still create other continuous effects. Continuous effects created by static abilities that would add the specified ability won't apply to that object.
