Conditional execution

Hello,
code sample:

resource "aws_cloudformation_stack_set" "config_role" {
...
  template_body = <<EOF
Resources:
 ...
EOF

resource "aws_cloudformation_stack_set_instance" "config_role_deploy" {
  stack_set_name = aws_cloudformation_stack_set.config_role.name
  deployment_targets {
    organizational_unit_ids = [data.aws_organizations_organization.org.roots[0].id]
  }
...
}

Issue:
any change to the template_body triggers update to all stacks
after that the aws_cloudformation_stack_set_instance triggers additional update

This is doubling the execution time.

How can this be avoided?

P.S. It appears, that i do need “instance” resource to deploy the aws_cloudformation_stack_set into existing AWS accounts.
