Add PnP-PowerShell Script step into your build pipeline:

When done, go to Tasks tab and fill in missing information (SharePoint site url, credentials, script type). Your resulting configuration should look like in the image below:
HINT: You can use your Variables with $() special syntax. For example $(sp_user) will pass username configured under Variables tab.
Use inline script or script file with your PnP-PowerShell code.
