Is it impossible to use Particle systems input data for vertex shaders?

I am wondering if its normal that I get the following errors when trying to use input data from a particle system inside the vertex shader of a material?

Error [SM5] (Node DynamicParameter) Invalid node used in hull/domain shader input!

Error [SM5] (Node ParticleRelativeTime) Invalid node used in hull/domain shader input!

Here’s my shader network showing the errors:

here’s a screenshot of my usage list for this material:

Dynamic parameter, particle relative time are both not allowed to be used in the tessellation part.
thats the gist of it.
