FAP with RB750G

I would like to know if I can configure a FAP in a RB750G .
If it is possible , somebody can tell me the procedure ?

what you mean FAP?

The Fair Access Policy (FAP) , I think that I should use the “queues” but I’m not sure

the simplest way is using simple queue which you can setting queue policy based on ip address or packet..
any method you can use, default (htb), pcq, sfq, etc.
better you read the User Manual, there is a lot of information about traffic control concept to queue your bandwidth.
