This is not possible. During creation of CSR, Openssl generate private key.

Hi,

 

While renewing existing certificate CSR, if we point existing key & export the CSR - will it generate CSR with existing private key

You can't generate private key with help of exiting CSR. I can suggest to choose below options.

 

Option 1: Generate new CSR and share to CERT provider and get cert.

 

Option 2: Check with Cert provider if they can consider exiting CSR(they have old csr) and share new Public Cert. Then replace exiting cert to new cert in F5.

 

Note: Take backup before making any changes for Options2
