They wouldn’t know yet, even if they were prepared to tell you! Decisions can be made right up until the day before a new quarter – and in fact beyond, as the quarters no longer mean what they used to. Additions and deletions now happen on a daily basis and rarely seem to be ‘held back’ to quarter days. They are more about price changes now.
I don’t know what the lead times are on Skoda Elroqs, but one option is to order the best model available now but if the VRS comes on the scheme cancel and reorder. However, I’d on,y do this if you would be happy with the lesser model. The VRS may never appear on the scheme and, even if it does, it may not appear until some months after launch.
