SSL with 4096 bytes

SSL certifcate I got from letsencrypt is 2048 bytes by default Can I request for certificate with 4096 bytes in lenght. If this is possible, can you help me what is the command I can use to get that?

Thanks

Yes.

That depends on which client you're using.

Am using nginx, acme-v02 and certbot to get and run ssl certs

--rsa-key-size N      Size of the RSA key. (default: 2048)

Yeah, I have tried that and sucessfull. Thank you
