Unable to set engine-strict flag with yarn

I am trying to force all devs to use particular version of node or higher.

I have

  "engines": {
    "node": ">=14",
    "yarn": ">=1.5",
    "npm": "please-use-yarn"
  },

I tried

1. .npmrc

engine-strict = true

2. .yarnrc.yml

ignore-engines:  true

but it led to following error when I run yarn install

Usage Error: Unrecognized or legacy configuration settings found: ignore-engines - run "yarn config -v" to see the list of settings supported in Yarn

How can I force devs to use particular version of node?
