Turn off 2G on phone

I have an S20 FE 5G phone that was recently upgraded to Android 12. I understand that there is a very dangerous 2G vulnerability called "Stingray". Is it possible to block or disable 2G on my phone?

 

Stingray is used by police for surveillance and not dependent on a carrier’s continuation of 2G service.  As such, it appears most cell phone manufacturer’s firmware does not allow turning off 2G unless jail broken.
