How to update existing AWS profile Value?

Question

I created profile on my new laptop.

aws configure list 

shows

     Name                    Value             Type    Location
      ----                    -----             ----    --------
   profile                <not set>             None    None
access_key     ****************FFAQ shared-credentials-file    
secret_key     ****************0lv7 shared-credentials-file    
    region                <not set>             None    None

How to set Value to borisjohnson? I tried

aws update-profile --profile-name borisjohnson

but that does not work.

It seems that Terraform does not recognize it as default

provider "aws" {
  profile = "default"
  region  = var.region
}
