My answer here may give some insight. I also ran into this issue: #33170 (comment)

Not sure if it's the same issue I'm seeing, but I'm finding that service-managed stacksets continually attempt to remove the administration_role_arn parameter on the stack set. But of course, this is unnecessary if it's a service-managed stackset (as opposed to self managed).

  # module.xxxx[0].aws_cloudformation_stack_set.xxxx[0] will be updated in-place
  ~ resource "aws_cloudformation_stack_set" "xxxx" {
      - administration_role_arn = "arn:aws:iam::000000000000:role/aws-service-role/stacksets.cloudformation.amazonaws.com/AWSServiceRoleForCloudFormationStackSetsOrgAdmin" -> null
        id                      = "xxxx"
        name                    = "xxxx"
      ~ parameters              = {
          ~ "Region"               = (sensitive value)
            # (6 unchanged elements hidden)
        }
        tags                    = {}
        # (10 unchanged attributes hidden)

        # (2 unchanged blocks hidden)
    }

@ohookins it's not, you can simply ignore that changes with lifecycle
lifecycle { ignore_changes = [ administration_role_arn ] }
