You need to install powershell-yaml module for that. Here is an example:

if (-not (Get-Module -ListAvailable -Name powershell-yaml)) {
    Install-Module powershell-yaml -Force
}

$yamlData = ConvertFrom-Yaml (Get-Content -Path .\data.yaml -Raw)

$yamlData is hashtable, so you can retrieve any object property from it.

For instance, if you have such content in yaml file:

name: DataObject
traits:
  - Green
  - Good
  - Round

value:
  dataArray:
    - FirstsPartOfData
    - SecondPartOfData

After reading you can access each property and array like this:

$yamlData.name
$yamlData.traits
$yamlData.value.dataArray
