No we will not support pirated copies of the game.

Trainer support is for legally obtained games listed under the Distribution(s) section of the trainer page, so...no, you will not.
The most recent update appears to be a trainer for Subnautica: Below Zero, not Forza Horizon 4.
Thanks for reporting, i have forwarded it and will be fixed asap.
