How do I describe jobs dynamically in Azure DevOps?

I have a number of jobs for different platforms I'd like to run in parallel. I'd like to build a different set of platforms for different situations (i.e. full build, smoke, pull request, etc.). How can I make a list of jobs dynamic based on variables?

For example, if this is one of the "hard-coded" implementations:

jobs:

- job: Platform1
  pool: Pool1
  steps:
      - template: minimal_template.yml
        parameters:
          BuildTarget: Platform1

- job: Platform2
  pool: Pool1
  steps:
      - template: minimal_template.yml
        parameters:
          BuildTarget: Platform2
        
- job: Platform3
  pool: Pool2
  steps:
      - template: minimal_template.yml
        parameters:
          BuildTarget: Platform3

How could I instead extract out a collection of variable sets, i.e.

[[Platform1, Pool1], [Platform2, Pool1], [Platform3, Pool2]]

And execute that on a pipeline like:

jobs:

??(Foreach platform in platforms)??

- job: $(platform[0])
  pool: $(platform[1])
  steps:
      - template: minimal_template.yml
        parameters:
          BuildTarget: $(platform[0])

You can define it in the parameters and loop it:

parameters:
  - name: Platforms
    type: object
    default:
      - name: 'Platform1'
        pool: 'Platform1Pool'
      - name: 'Platform2'
        pool: 'Platform2Pool'
jobs:
- ${{ each platform in parameters.Platforms}}:        
  - job: ${{ platform.name }}
     pool: ${{ platform.pool }}
     steps:
         - template: minimal_template.yml

You may alos use 'jobList' type for template parameters:

parameters:
- name: 'testsJobsList'
  type: jobList
  default: []

jobs:
- ${{ each job in parameters.testsJobsList }}: # Each job
  - ${{ each pair in job }}:          # Insert all properties other than "steps"
      ${{ if ne(pair.key, 'steps') }}:
        ${{ pair.key }}: ${{ pair.value }}
    steps:                            # Wrap the steps
    - ${{ job.steps }}                # Users steps

And then:

trigger:
- none

pool:
  vmImage: 'windows-latest'

jobs:
- template: deployment-template.yml
  parameters:
    testsJobsList: 
      - job: Platform1
        pool: Platform1Pool
        steps:
        - template: minimal_template.yml
      - job: Platform2
        pool: Platform2Pool
        steps:
        - template: minimal_template.yml
