Conditional Processing in Dockerfiles based on template parameters

Is there any way of applying conditional processing in dockerfiles?
I would like to make the content of dockerfiles dependent on template parameters but I've been not able to find out in documentation how to make it. It seems dockerfiles are not included in the documentation about conditional processing and default notation is not valid. Thanks!
