Your 2018 Dell laptop is experiencing a 'coil whine' sound.
Used an older Asus laptop with a coil whine sound. Dell forums suggest others face similar problems. My Precision M6700 sometimes produces noises near the GPU VRM, which is normal. Likely outside warranty coverage, as coil whine is usually not.
