Setting limits.single_field_size_bytes in Dremio Cloud Standard

Hello!

We are running tests on Dremio Cloud Standard to see whether we can replace our current kubernetes-based Community Edition setup.

We would like to set limits.single_field_size_bytes to a more convenient value for our datasets (99k), as suggested here

We tried both

alter session set limits.single_field_size_bytes = 99000;

and

alter system set limits.single_field_size_bytes = 99000;

but we get

Permission denied. Support keys can be set only via support console.

Is it possible to raise this limit in Dremio Cloud Standard?

Thanks for your help!
