Exchange Macbook pro 256 GB with a Macbook pro 512 GB

Hello,

My name is Shiper Ahmed Chowdhury. I bought a MacBook Pro M1 256 GB from O2. Now I think the storage is not enough for me. But I have been using it since almost 3 months. Can I exchange it now with a MacBook Pro 512 GB from O2. 

Thank You.
