Conditional environment variable creation inside a kubernetes_deployement

Hello there, so i am looking to deploy my app on my eks cluster using kubernetes_deployment, it works like a charm for one specific app.

Now i am looking into generalizing my deployment to use it on multiple apps with minimal differences, one difference is that for app A i need to set git credentials as env vars and app B i don’t need those
I am creating these env vars from a secret like so.
My question is can i have these be conditional ? IE if (app A => create my env vars ) if app B don’t

      env {
          name = "GIT_USERNAME"
          value_from {
            secret_key_ref {
              key  = "username"
              name = "my-secret"
            }
          }
      }

      env {
          name = "GIT_PASSWORD"
          value_from {
            secret_key_ref {
              key  = "password"
              name = "my-secret"
            }
          }
      }
