Antonio,

I believe the correct syntax is:

   ds.AddBand(options=['subClass=VRTDerivedRasterBand'])

The options should be a list of name=value pairs.  Your extra double
quotes within the string will make the class name comparison fail
since you are effectively passing "\"VRTDerivedRasterBand\"" in C
terms.

Best regards,
