Trainer flag request (run validation after N epochs of training)

Is there a way to indicate to the trainer to start the validation after X completed periods of training only? Not the interval that is already possible by means of certain flags, but to indicate it after X specific epochs. Something like: validate_after_n_epochs…

I think that would be useful for example if you want to make a training faster or if you know before hand validation metrics won’t start improving after N epochs.

I guess the only way to do this at the moment is to add a condition inside validation_step and on_validation_epoch_end.

Thank you!
