Does this extension automatically load environmental variables from .env file if present? If yes, how do I stop that?

I am trying to hunt down why my VSCode starts up with all the environmental variables preloaded from a local .env file.
What I mean is that I have a .env file at the root of my project:

MY_VAR=yep

and when I launch VSCode I do

❯ echo $MY_VAR
yep

I do not want that.

Is this extension the one loading those vars, and if yes how do I stop it?
Thanks for your time

Sorry my bad, it looks like it's baked into VSCode itself
