How to cache files from file storage on SSD in CentOS 7?

Question

Solid State Drives

Hello.
We want to implement caching of "hot" files on SSD on a server with CentOS 7 OS.
Read about FlashCache, EnhanceIO, dm-cache.
The first two are very old, as far as I understand, dm-cache uses its own file system for both SSD and file storage itself.
I would not want to change the file system, so tell me working solutions for such purposes.
Functionally, based on the capabilities, I really liked EnhanceIO.
Is there anything more modern?
