How can I change the certificate type if I request or renew it?

[Chrishan68]

Dear all,

the request or the renewal process for my certificates are working fine in npm and I also found the folder where the pem files are stored.
I am also able to convert the pem files with openssl to crt or pfx certificates with the private key. But they are not compatible with Microsoft Exchange. Therefore I want to change the key size, public key, public key parametes and key usage. But where can I find the config file for this and which parameter names and values are valid?

Thanks in advance!!!

as far as I am aware of, this is only configurable inside the docker / certbot.
see: https://eff-certbot.readthedocs.io/en/stable/using.html#id20 and https://eff-certbot.readthedocs.io/en/stable/using.html#id36
