Adding Content-Disposition after an AWS presigned url have been generated

As Presigned url suggests it is a signed url that can be validated using the signature. I am able to set the Content-Disposition header on the ResponseHeaderOverrides in order to change the filename when downloading the file using the persigned url.

            GetPreSignedUrlRequest request = new GetPreSignedUrlRequest
            {
                BucketName = bucketName,
                Key = objectKey,
                Expires = DateTime.UtcNow.AddMinutes(duration),
                ResponseHeaderOverrides = new ResponseHeaderOverrides { ContentDisposition =$"attachment; filename=\"MyNewFileName.doc\""}
            };

Is it possible to generate the presigned url and then when using that url use a Content-Disposition header or query param in order to ensure a file downloads with a certain name. Currently the desired file name is not known at the time when the presigned url is generated.

No, this is not possible since the specified header is included in the String to Sign.
