Is it possible to control the saving of best_models?

When training VITS, especially when fine-tuning a dataset using one of the pretrained models and when dealing with a very small dataset (for example, 130 audios) the best_models are saved quite often. The least I've noticed is that it saves a best_model every 16 steps, so neither save_step, save_checkpoints, nor save_best_after solve this problem, so I'm coming to the conclusion that this is something that can't be controlled in the config. This is important as I'm training from colab and saving all work to Drive, so it consumes a lot of storage space.
