Typescript - How to make sure array of possible values has only one value of certain type

So I have an enum like this:

enum StringsVals {
  'aaa',
  'bbb',
  'ccc'
}

and I define a variable x which can be an array of enum values like so:

const x: (keyof typeof StringsVals)[] = ['aaa', 'bbb']

Is there a way I can make sure that x only contains those values and they are unique in order to avoid this for example?

const x: (keyof typeof StringsVals)[] = ['aaa', 'bbb', 'aaa', 'aaa']

Or there is so much that Typescript can do?

enum StringsVals {
  'aaa',
  'bbb',
  'ccc'
}
const x: (keyof typeof StringsVals)[] = ['aaa', 'bbb']
