terraform backend input variables

Question

I am trying to use terraform scripts that could generate multiple instances of infra having different states and variables . Currently i am testing if this is possible using terraform backend with local . Eventually we plan to move to azure vault to store multiple terraform states

I am aware that backend doest have variable support. But is there anyway i could pass the path variable to terraform init ?

    *terraform {
  backend "local" {
    path = "./states/"${local.prefix}state.tfstate"
  }
}*

Currently we are using Kapitan for handling such scenarios.

Essentially you have an inventory with all valuable parameters, keeping the TF modules in a /components directory ( basically your templates ). During kapitan compile all replacement would happen and your ready for execution TF code with proper variable replacement would be stored in /compiled.

This gives you the flexibility to also modify on run K8s manifests, basic scripts ...
