Hello Aleksandr,

Thank you for reaching out and I am happy to help!
The option in the W3 Total Cache – Cache URIs with query string variables is disabled by default if the caching method you are using for Page Cache is Disk: Enhanced
This option is available with Disk Basic or memory-based caching options.
However, you can still manually add the query string when using Disk: Enhanced in Performance>Page Cache>Advanced>Accepted query strings: field, and this will ensure that the query strings are cached even with the Disk: Enhanced caching method.

Let me know if this helps!

Thanks!
