Is it possible to set the output size to 256*256

HI:
I have LR with size 6464. I would like to perform x4 SR and output 256256. Is it possible for the provided pretrained model? Since the default output size is 512*512

You can first upscale to 512 and resize to 256. Directly getting 256 will lead to poor quality since the diffusion prior is trained on 512.
