restore the BIG-IP to its previous state (where server.csr displays No CSR) without impact

Hello, I made same  mistake and filled in the CSR file (server.csr) under: System > Certificate Management > Device Certificate Management > Device Certificate Signing Request Before this change, the server.csr entry already existed in the GUI and its status was: No Certificate Signing Request After I filled in the CSR parameters, I would like to restore the BIG-IP to its previous state, where server.csr appears with the message: No Certificate Signing Request I would like to remove the CSR information safely without impacting the existing configuration. I performed the following checks: tmsh list sys crypto csr tmsh list sys crypto csr one-line tmsh list sys crypto csr server.csr None of the above commands return any output. I also found that the file exists only at: /config/ssl/ssl.csr/server.csr Furthermore, searching for server.csr under /config did not show any reference to it in the BIG-IP configuration files. If not, what would be the recommended and safest procedure to remove the CSR information and restore the BIG-IP to its previous state (where server.csr displays No Certificate Signing Request) without impacting the current Device , i want to remove it from cli using this command: 

rm /config/ssl/ssl.csr/server.csr 

 Thank you in advance
