I think it would be nice to generalize this option to all probe capture. If there is a need to split it per probe type, that can be done later.

Rename double_sided_gi to use_backface_culling_probe.

Do not move show_transparent_back here (it is not the same as a backface culling).

Rename `double_sided_gi` to `use_backface_culling_probe`. Do not move `show_transparent_back` here (it is not the same as a backface culling).

Don't pass blender_mat here. You can get the material from the gpumat using GPU_material_get_material.

Why? Most pipelines receive the blender_mat directly as parameter.

GI is not a widespread accronym in the blender codebase. Use "probe capture" instead.
