How to Dynamically assign the runs-on value in the github actions

Question

name: test if conditions
name: test if conditions
on:
  push:
    branches: [master, test]
env:
  TEST_BRANCH: "test"
  EMPTY_VALUE: ""
jobs:
  test-conditions:
    runs-on: ubuntu-latest
    steps:
      - name: simple evaluation on test
        run: echo "runs"

#eg) for test branch => runs-on: ubuntu-latest
     for master branch => runs-on: ['self-hosted', 'products', 'latest']

is it possible to dynamically load the runs-on in the same workflow ?

${{ (inputs.shouldUseSelfHosted) && fromJSON('[ "self-hosted", "Linux", "X64" ]') || 'ubuntu-latest' }}

#eg) for test branch => runs-on: ubuntu-latest
for master branch => runs-on: ['self-hosted', 'products', 'latest']

Complete workflow file will be looks like:

---

name: test on multiple runners

on:
  push:
    branches:
      - master
      - test

jobs:
  simple-test:
    # if affected branch is 'test' then runs on 'ubuntu-latest' else self-hosted...
    runs-on: ${{ github.ref_name == 'test' && 'ubuntu-latest' || fromJSON('["self-hosted", "products", "latest"]') }}
    steps:
      - name: simple evaluation on test
        run: echo "runs"
