Indeed. The architecture contains a 32-bit backward compatible component (that is optional in 64-bit ARM servers[0], but included in the one that you are using) and it is technically possible to install the libraries side by side. However the upstream that Cent is using is intentionally engineered never to support that case. It sounds harsh now, but there is no 32-bit server legacy, we have 32-bit VMs, you could build a 32-bit container if you really wanted, and in a couple of years we will all be wondering why we ever cared about 32-bit in the first place on ARM servers.


[0] That was my doing. It is time to move on from 32-bit and not create a legacy, dragging everyone's power/performance efficiency down having to implement expensive 32-bit backward compatibility that people don't actually need. Recompile the software and move forward.
