Replace AVAST/AVG Root Cert with my own

I am sorry to inform that it is not possible to root SSL/TLS web scanning using your own root cert.

Our certificate will be always forced if SSL scanning is enabled.

Hi, I would like to know how can I replace your Root Cert used for SSL/TLS Web/Mail scanning (decryption) with my own Root Cert. 
 

Thanks,
