We got this working:

stages:
  - stage: Build
    displayName: Build

    jobs:
      - job: build
        displayName: EAS Build for Android and iOS

        pool: Default

        steps:
          - checkout: self
            clean: true

          - task: NodeTool@0
            displayName: "Install Node.js"
            inputs:
              versionSource: "fromFile"
              versionFilePath: ".nvmrc"

          - bash: npm ci --no-fund
            displayName: "Install NPM dependencies"

          - bash: npm install -g eas-cli
            displayName: "Install EAS CLI"

          # note: `platform all` here means iOS and Android, not Web.
          - bash: eas build --platform all --profile preview --no-wait --non-interactive
            displayName: "Build on EAS"
            env:
              EXPO_TOKEN: $(EXPO_TOKEN)
