Cross platform/technology/language Configuration Management for microservices

Question

We have our technical stack spread across Spring-boot, Node and PHP8.0, each of the systems have their own configuration management flavours as below: Spring we are using Spring config server which is natural and allows encrption profiling etc. Node we are using npm-config and for PHP it is mostly using environment files on different environments. I want to know and understand if we can have one central configuration management repository if not server which could be used across the platforms. Or if we were to use spring config store can that also be used as source for configurations for the other two stacks.

Any suggestions or recommendations would be highly appreciated.
