Sure, although you could also say יותר ממספיק (another word for "enough" being מספיק).
Honestly, if someone could explain the differences between די and מספיק, it would be much appreciated!
Both mean enough. די is commonly used as an exclamation "Enough!", or in phrases like here.
In a normal sentence using the word "enough" one would use מספיק.
When I write os instead of is, it is because it is difficult to write on my cellphone. Os is not a word! Just a slip of the thumb
