Cache option not showing

First of all i got a TCL C745 with Google TV running with Kodi 21. Now i connect my NAS via SMB and everything works fine so far but sometimes it just keeps caching while i watch movies.

Now i did read about the cache settings to change them and maybe it works better.

The only problem is i dont have the Cache setting under Services.

Is it only Possible on Windows?

Thanks for ur help and best regards!
