It would be complicated if you doesn't have the files source code, or you can look for someone to code a .dll for you with those command and hook it into your gameservers. But there is also a way if you really like old version you can just simply downgrade high version with lot of commands like for example downgrade season 4 or 5 files that have those command to your liking if you like s3ep2 or 97 you can disable some features of higher version to make it look like lower version.
