No, I was not able to get a definite answer on this. However from researching, it seems like I can choose either standard or itemized deduction. If later on spouse files for this year, they will probably need to match whichever deduction I took. It's just that both cannot take different deductions, which in my case is irrelevant since he won't be filing (no deductions). The only catch is you will have to paper file and mail return.
