I through that it was not supported in SuiteSparse but it's not the case (DrTimothyAldenDavis/SuiteSparse#136).
We could do something similar to SobhanMP/SuiteSparse.jl@7093e4a and add the additional two vectors Y and E in the Julia structure.

CHOLMOD_UserGuide.pdf <- pages 119-120.

I'll try to get this added for 1.9. If you need it in previous versions I'm entertaining a CHOLMOD.jl separate from SparseArrays.jl

Thanks @Wimmerer! No, I don't need it for previous versions. If you can add it for Julia 1.9 or 1.10, it's perfect.
