How to set AWS ALB (application load balancer) LCU (capacity units) via terraform

How to set the AWS ALB (application load balancer) LCU (LoadBalancer Capacity Units) via Terraform configuration files?

I was unable to find anything in the AWS CLI docs and the issues search in the aws provider as well.

Any eyes on this on how to set the LCUs?

Any help from anyone who might have faced a similar issue?
