set variable variable to previous set variable

[gorkemgoknar]

How can I use previously set input value, which in below example "inputs.tag" is set by auto-deployer, but I want to also get the value of "inputs.tag" (do not want to modify CI, want to access an already set input variable)
Thank you.

include "envcommon" {
  path = "${dirname(find_in_parent_folders())}/_envcommon/services/myservice.hcl"
  merge_strategy = "deep"
  expose = true
}

# ---------------------------------------------------------------------------------------------------------------------
# Locals are named constants that are reusable within the configuration.
# ---------------------------------------------------------------------------------------------------------------------
locals {
  my_other_local_value = "SomeValue"
}

# ---------------------------------------------------------------------------------------------------------------------
# Module parameters to pass in. Note that these parameters are environment specific.
# ---------------------------------------------------------------------------------------------------------------------
inputs = {
   # tag of docker container, which auto-deployer sets automatically
   tag = "main-abcd1234"

   env_vars = {
       release_tag = "main-abcd1234"   # want to set it to inputs.tag (or TF_VARS_tag environment variable which above would set)

   }
