Supported RSA Key Lengths for Encrypted SQL Connections

I'm having trouble finding any documentations regarding supported key lengths for RSA certs to encrypt SQL connections. Our internal CA is issuing certs with a 4096 key length and that seems to work with our 2019 SQL servers, but I cannot seem to get anything lower than 2019 to see the certs in Configuration Manager. My hunch is that 2017 and below do not support a 4096 key length but I'm not able to find any documentation saying what is actually supported so it's only a guess right now. Does anybody have any documentation showing what is supported by each version? Thanks.
