I wonder if you could step back and explain the big picture, as I'm not
really following this.   As I understand it:

  usually asterisk is used as a pbx

  STIR/SHAKEN is a protocol run between carriers to prove the authority
  to use the claimed callerid

  when someone gets service from a carrier and connects to it from
  asterisk, I would expect the carrier to basically filter the claimed
  callerid to be from the set of values recorded with your account as
  legit, and for the carrier to do the STIR/SHAKEN authentication.

So I wonder if your asterisk instance is connecting to the PSTN as a
top-level carrier, or, more likely, I am confused in some way.
