How to create CSR for MSSQL?

I've never had to deal with SQL that much before, but I've inherited a few SQL servers that I need to get TLS certs for. The main issue I have is how exactly to even create the CSR? Is there any tool in SQL Server 2017 to do this like there is in IIS, or is there some secret method only known to DBA's. Even the Microsoft docs seem to presume you've generated a CSR, or know the voodoo for it.
