Which Visa can tier-1 dependant can be switched to?

Hi,
Can someone help to guide what are the options to extend visa for tier-1 entrepreneur dependant visa holder please? Can it be switched to different route on its own? I am asking as the couple had divorced since and the dependant needs a way to extend her visa in the UK if possible.

Presumably they have informed HO on the prescribed form that the relationship has ended??

The dependent would have to find a visa they qualify for. Very few that can be applied for within the UK though.

I don't believe there is a 'dependent' visa category that applies.
