Modify tire size via obd2 at home?

Is there any app with an obd2 reader like Jscan that I can change the tire size? When I bought my 25 it came with bigger tires and my speed is 1 mph higher than actual and want to get this fixed for odometer and etc reason.

Google doesn’t really say and don’t want to have to go back to dealer and wait in the dealership if I can do it at home.
