Expert Answer
They can be accompanied together but not in parent nucleus but the nucleus formed after emitting out any particle can emit both alpha and beta particles together.
They occur in rare cases usually in isotopes

There are radioactive substances that undergo both alpha and beta decays, for example the isotope polonium-217 goes under alpha decay 95% of the time and beta decay 5%. Now as far as your question of both decays at the same "time", I don't know any reason off hand why such isotope couldn't emit both alpha and beta particles at the same time.
