Sorry I think the community is a bit stuck trying to figure out what you are asking.
So lets start by answering the question that we think you asked - and then if not - having you restate the question.
To set a Mikrotik to utilize a Radius Server - you simply go to the Radius menu and enter in the user/pass and ip address of the Radius Server you are looking to authenticate against.
Both then can be setup as a hot spot using the basic HOT SPOT setup as outlined in the WIKI . You could also watch some of the videos from TIKTUBE.com - like this one - and then adjust to use the Radius server option

I have a feeling your asking something else - If so, can you help us help you by restating the question?
