Is there a model that pooled_output=256?

I used a pre-trained model (bert-base-chinese) for fine tuning, but I found that pooler_fc_size=768 is too big, I want to make it smaller, but I don’t want to train from scratch, is there a trained model on the forum (pooler_fc_size=256)?
I want to find a model(pooler_fc_size=256)
