Is there a way that I can pass variable into ds_select_dst(set, alg) on the set parameter so I can query from database table for setid; for instance, ds_select_dst("avp(customer_setid)", "4"). I've tried, but it did not work. Please advise.
A look in modules/dispatcher/dispatcher.c reveals that ds_*() functions do not parse pseudovariables, which is a problem with a lot of existing Kamailio code. Any arguments you pass to it will be interpreted as literal strings.
In short, you can't do that. You may wish to put in a feature request to update these functions to take pseudovariables.
