Is there a way to write a groq query that checks if a boolean is true, and if so, returns an array of referenced documents? (example use case, on a homepage, I want to allow...

{ features[_type match 'blogEntries'] { 'posts' : *[_type == 'post'][0..2] { ... } } }

{
  "posts": *[_type == 'post' && 'blogEntries' in (^.features[]._type)][0..2],	
} 

export async function getAllStaff(num) {
  const result = await client.fetch(
    `*[_type == "staff"] | order(firstName asc, lastName asc) {
      firstName,
      lastName,
      slug,
      image,
      position,
      _type,
    }[0..${num}]`
  );

  return result;
}

export async function getStaticProps() {
  const allStaff = await getAllStaff(8);

  return {
    props: { allStaff },
    revalidate: 120,
  };
}
