Can i replace HAVE with ARE?

This is film critic Robbie Collin for The Telegraph:

Whether Listen Up Philip is a significant step up for Perry or just business as usual, I can’t tell you: his previous two features, Impolex and The Colour Wheel, have yet to be released in the UK.

What difference would it make if have is replaced with are ?

his previous two features, Impolex and The Colour Wheel, have yet to be released in the UK.

This can be simplified to “They have yet to be released.”

They have yet to be released. This is the causative passive – the arrangements for their release have not been made yet (by someone) -> Someone has not yet made arrangements for their release.

They are yet to be released – This is the passive – they have not yet been released (by someone) – Someone has not yet released them.
