Increase number of partitions above 1024

I'm using riak master version on riak github (riak_kv_version :
<<"2.1.1-38-ga8bc9e0">>)
. I don't use coverage queries.

When I try to set the partition count over 1024, it suggest me to do it via
advanced config (in cuttlefish schema for riak core, there is a validation
to see whether it is above 1024 and if so they give this suggestion). But I
don't know how I can add this parameter to advanced.config.

Thank you very much!
