TPMS sensor Mhz

Could someone run my vin and tell me what Mhz my sensors are?  I was told that GMC switched part way through 2020.  TIA

That would be odd, given that the trailer TPMS works om the same frequency. Where di you get that info? I know mine are 433 mhz...Truck was built in January 2020.
