"If-None-Match" header field is automatically being inserted in request header

If-None-Match header with "e-tag value" field is automatically being inserted into AWS CompleteMultipartUpload request headers by NeoLoad. How do I stop NeoLoad from automatically inserting this field into my request headers?

We tried Population settings, the 'Handle cache' setting : New user
But no luck.

Thanks in advance,
