You have 3 corners, so it is hard for me to understand how UV will become a nice mesh, but you can certainly divide in 3 parts and have a surface with 4 sides. So at the end 3 surfaces.
You could get a nice mesh using Meshmachineor Meshmachinestatic !
Here an example with generation of clean surfaces with clean quad meshes at the end.
Some difficulties with shatter, so if a problem change on a panel 0 by 1 or 1 by 0.
