To do Tacacs+ TLS Based Auth I need to deploy Cert into the Devices ( Cisco IOS-XE ) in PKCS Format following method 2 mentioned at below URL

Deploying cert in every device individually will be cumbersome. Since, if I can deploy certs ( PKCS format ) to device from DNAC ? Note that Devices are managed from DNAC so DNAC has reachability to network devices for which TLS Based Tacacs+ Config will be done.
