Can I refuse to sign a kindergarten transfer?

Of course. Adjustment refers to the fact that the reported major is not enough, and you choose to change to the one that is not full. Kindergarten transfer is just a form. Family members who are not satisfied with the transfer method can refuse it. They can ask the kindergarten to put their children in a good class, or they can ask for a refund if the kindergarten refuses to transfer. This is in line with all legal procedures.
