Anyone knows how to set default plugin parameters?

Is there a way to set default plugin parameters that apply to every new vGPU instance instead of having to set them individually for each new instance (as indicated in the docs for KVM)?

I would like to have unified memory enabled by default for every new vGPU VM that is instantiated, so having to set this parameter individually hurts automation. Additionally, from what I have tested the VM has to be stopped for the changes to go through.
