Ioncube. How to fix encoder and loader compatibility?

Question

PHP

Good afternoon.
There was a problem, you need to encode the file on the server. I've never done this, so I started asking Google.
Multiple archiving was discarded as inefficient. There are many questions with Zend. I settled on ioncube. Everything is cool, cool, everything works locally. However, it gives an error on the server.
cannot be decoded by this version of the ionCube Loader
The server is running version 4.7 of the loader. At the moment, 5.3 is already being installed.
It is clear that during coding I can choose both the php version and the version of the encoder itself.
However, I exposed both 7.3 and 5 versions and still gives this error on the server.
Only FTP access to the server without the ability to edit the php.ini file. Accordingly, I cannot ask the hosting to update the loader.
I read that you can enter a new loader in the local php.ini, but this file will simply break.
The question itself. Is it possible now to somehow encrypt ioncube for such an old version?
