AWS EC2: does Network Load Balancer have security groups?

In the doc: https://docs.aws.amazon.com/elasticloadbalancing/latest/application/load-balancer-update-security-groups.html It syas the following when editting the security group of load balancers:

Update the associated security groups
You can update the security groups associated with your load balancer at any time.

To update security groups using the console:

1. Open the Amazon EC2 console at https://console.aws.amazon.com/ec2/.

2. On the navigation pane, under LOAD BALANCING, choose Load Balancers.

3. Select the load balancer.

4. On the Description tab, under Security, choose Edit security groups.

5. To associate a security group with your load balancer, select it. To remove a security group from your load balancer, clear it.

6. Choose Save.

However, for my Network Load Balancer, I cannot select the "Edit security groups" option. It is greyed out:

How to edit its security group then?

Currently requests to the NLB cannot be delivered to the EC2 instance in the target group, because of security group configurations.

Why can't I edit??

No, Network Load Balancers do not have security groups. You should add Security Groups directly to the EC2 targets based on IP addresses or CIDR blocks.

See: Target Security Groups - Elastic Load Balancing
