RBAC Trial

Tell me, is it possible to somehow get the RBAC service packages in the form of a trial for dividing rights in the MaaS service?
There is a mention of it in the docks, as well as in the price list that the RBAC service for Mac is only available by subscription - but which subscription will be enough ?
Now MaaS 2.7 is deployed on a single virtual machine, I would like to understand its capabilities in terms of sharing access rights to the poured machines.
