Sorry, but no.

STIR/SHAKEN only affects voice calls.  It has nothing to do with SMS.

As several other people have said, if you're sending safety critical SMS messages, use
a real SMS service, not a carrier's courtesy low volume e-mail gateway.

SMS services are not free, but they are not expensive, typically about 1/2 cent per message.
