Can’t be done through OBD. Several companies offer this service through mail-in of the cluster, on eBay mostly.

*Technically* in some states/countries changing the mileage on a cluster is illegal no matter what, so YMMV. What you’re supposed to do when your cluster breaks in most of the US for example, is to get a sticker from the DMV that shows the discrepancy between indicated and actual mileage.
