Specify encode parameters in Upload via api/upload file

Hi Team,
Is there a way to specify the encoding paramters (resolution/bitrate) required for different encodes while uploading a file via any of the upload via file or upload via http url method ?
As I understand, we just upload the video, and cloudfare automatically creates the encodes on basis of bitrate ladder. But I would be more interested to understand if it would be possible to provide the paramters ourselves as per our own requirements.
Thanks
