Actually, you can use vectors from the following scenario : 

[AES-128 no df]
[PredictionResistance = False]
[EntropyInputLen = 256]
[NonceLen = 64]
[PersonalizationStringLen = 0]
[AdditionalInputLen = 0]

Here, it says that there is a nonce of length 64, but it is not used as
there is no nonce used when DF is not used... So even though this scenario
provides a nonce value, it is never used.

Trust me I tested it myself ! (you can also verify in SP800-90 that no nonce
is used when no df..)

Cheers !
