Hi @Sheng Xu ,
Just wondering if you have Edge Subscription after you install Edge Transport servers?

It is recommended that you refer to this link for Edge Subscription and try get-exchangeserver again to see if you can get Edge Transport servers：Edge Subscriptions | Microsoft Learn
Hope the above suggestions are helpful to you！
