Windows SMB Caching

Hello, I'm using Windows Server 2022 as storage server with a lot of SMB shares. Whole network is 10Gb ethernet/SFP+ and storage on server is based on SSD array so clients can benefit of full 10Gb speed. Problem is SMB caching "function" which is on windows systems enabled by default. This "function" cause speed inconsistency (and high RAM usage on server side) with file transfer over SMB protocol. To disable (bypass) this "function" I need on every client PC in network to map shared drives they need via cmd and use /WRITETHROUGH parameter.

So my question is: Can this SMB caching feature be disabled on server side permanently?
