I am married. My wife has left and resides out of country with no income. We do not have children Can I file married joint even if I do not support her?

Yes.  If you were married as of 12/31/22, your filing options are Married filing jointly or Married filing separately.   And it is almost always better to file jointly.   Is your wife a US citizen?   See this discussion if she is not.

Thanks. As I posted before Joint reurn technically requires her signature or a pin number for electronic return. Since I have no communication with her she does not know that I file joint return by creatinga pin on her behalf. Will not this be unacceptable to IRS?

You can't file a return for someone without their permission. While the IRS may not know, she could turn you in for identity theft. It may be worth giving her a call or better yet, a text or email, where you can have proof that she is willing to let you file joint.
