Can an internal load balancer be deployed to one subnet? (AWS Cloud)

Question

I see AWS Cloud load balancers in 2 categories:

By Traffic - Internet and Internal LBs

By Use - Application, Network and CLassic LBs

I want to deploy an internal load balancer into one private subnet and ask it to only distribute traffic among the instances in that subnet. Is that possible?

I know that application LBs must be deployed to 2 subnets. Is there a configuration that allows deployment to only one subnet?

Unfortunately, not for ALB.

However, you can use 1 subnet with NLB and CLB.
