Modern rock versions do not have that limitation. Relying on wiki pages
for documentation carries elevated risks, especially when reading old
pages, but introduction of large object support was documented at
https://wiki.squid-cache.org/Features/LargeRockStore

A better starting point may be cache_dir documentation in your
squid.conf.documented generated for your Squid version.


HTH,

Alex.
