is it possoble to apply I-ViT to PTQ too?

I thought I-ViT works based on PTQ when I read the paper but your code and readme shows that it's based on QAT.

If I have the quantized int8 weight after PTQ(using like pytorch-quantization or some SOTA methods like FQ-ViT or RepQ-ViT), can I use the weight with your code?

thank you.
