In that case you will need to wait for it to arrive before you can create a MyDMV account. You can still change your address, though.
I'd like to know if it is possible to get a replacement license at a DMV office and get an Enhanced or REAL ID?
You are not obliged to get an Enhanced or REAL ID but starting in October 2020, if you have a Standard license, you will not be allowed board a domestic flight unless you have your passport
Do you currently have a Standard license?
