Split a bend for a partial unfold

Hello

Is there any way to split a bend for unfold only partially?

Yo can see what I want to do in the attached part.

My intention is to get this piece by making a sufrace or a plane to divide the external part of the bend after the cutout and unfold them keeping the center bend.

Thanks.

Have a good weekend

Regards
