I use hot backup to back up a shard cluster. Now I want to restore one of the shard data to a stand-alone database. What should I do

MongoDB Percona Server for MongoDB
1

I put the data into the data path of the standalone database, but found that the startup failed. After checking the log, I found that I would always try to connect to the Config of the sharded cluster

The version used is 4.4.8

Found the problem ，I still added the role of shard in the configuration file
