Hi Evgeny,
Thank you for reaching out to us.
I'm afraid that there's no possibility to select Ad information like name, id and labels with  "Performance max" advertising channel type, as it already stated in the 
documentation you have provided.
However, For the different business objectives that can be achieved through Performance Max campaigns, you can check out our 
optimization tips for Performance Max . These tips are equally applicable to Performance Max campaigns created by the Google Ads API. You may check this 
documentation for more information.
Best regards,
