Set environment variables in `environment.yml`

Can I set environment variables in environment.yml files in conda environments?

Conda lets me save environment variables in environments via the env_vars.sh script, but is there a way to automate the process of creating env_vars.sh files in the activate.d, deactivate.d directories according to some specification of environment variables within environment.yml, for a reproducible environment with, say, MKL_THREADING_LAYER=GNU?

It looks like this was added in Conda v4.9!

There is documentation at https://docs.conda.io/projects/conda/en/latest/user-guide/tasks/manage-environments.html#setting-environment-variables

Environment variables set using conda env config vars will be retained in the output of conda env export. Further, you can declare environment variables in the environment.yml file as shown here:

name: env-name
channels:
  - conda-forge
  - defaults
dependencies:
  - python=3.7
  - codecov
variables:
  VAR1: valueA
  VAR2: valueB

Older versions of conda will complain;

EnvironmentSectionNotValid: The following section on 'environment.yml' is invalid and will be ignored:
 - variables
