Is it possible to get a list of just the environment variable (names) that are used from `dotenv`?

I have the following taskfile 
version: '3'

dotenv:
  - .env
  - .env.example

tasks:
  default:
    cmds:
      - task --list

  show:env:names:
    desc: Show environment variables
    cmds:
      - # ...
version: '3'

dotenv:
  - .env
  - .env.example

tasks:
  default:
    cmds:
      - task --list

  show:env:names:
    desc: Show environment variables
    cmds:
      - # ...
With a .env like this 
HELLO=world
HELLO=world
And .env.example like this 
HELLO=darkness
WELCOME=back
HELLO=darkness
WELCOME=back
Is it possible to get a list containing HELLO and WELCOME ? The actual values are not that relevant, I'm just interested in getting a list of environment variables names so I can use it with envsubst.

Unfortunately, we don't have any way to get that list currently
