How to use the sharp.simd function in sharp

exports.process = function (fullImagePath, fullImagePathResult, size, callback) {
  // Disable experimental SIMD support - this is the default behaviour
  sharp.simd(false);

  sharp(fullImagePath)
    .resize(size[0], size[1])
    .toFile(fullImagePathResult, callback);
}

sharp.simd(config.imageable.simd);

export async function downloadImage (url) {
  const response = await rp.get(url, { encoding: null });
  return response

export async function identify (buffer) {
  try {

    return transformer.metadata();
  } catch (err) {
