Update the configuration by running the following command:
sudo microk8s.config set dqlite.tls=false
Step 2: Generate New Certificates
Generate new TLS certificates for dqlite using the following command:
sudo microk8s.dqlite cert gen
Step 3: Restart MicroK8s
Restart MicroK8s to apply the changes:

Update the file contents to:
tls: false
Regenerate Certificates with Custom Configuration
