Found a workaround for now. …not pretty, but it works 🙂

const outwardSecurityGroups = pulumi.output(aws.ec2.getSecurityGroups({
      tags: { 'aws:eks:cluster-name': clusterName },
    }));


    new aws.ec2.SecurityGroupRule(`my-rule`, {
      ...
      securityGroupId: outwardSecurityGroups.ids[0],
    });
