Hello,
I'd like to use RidgeCV to find the optimal alpha for each colunm
(ntargets) of the DV variable.
It lloks like itthe fit() computes a single alpha. Is there a way to
compute one alpha per column?

context is fMRI data, so I am running the Ridge regression in about 200.000
voxels.

Indeed , this is basically what I told you (you do not be need to copy
textbook stuff: I taught probas/stats) : these are mostly problems for
*inference*.
