Is there a verb for removing the mean or DC component of a signal? I am trying to name a flag for doing just that.
"Normalize" can mean many things, so I don't think that would be a good choice.

I've heard this referred to as demeaning a signal, or applying a DC notch (or, in some more hardware-related domains, a DC block). More generally, it might be called just highpass filtering the signal to remove the DC component.
I've heard the word centering for setting the mean of a signal to 0.
I've heard this called detrending. Although DC removal is a subset of what this means, the Mathworks refers to it in their detrend
function:
The MATLAB® function detrend subtracts the mean or a best-fit line
(in the least-squares sense) from your data. If your data contains
several data columns, detrend treats each data column separately.
A seldomly-used term is symmetrization, with accounts for removing a central tendency value (could be the average, the median, the midrange, depending on the loss function to minimize).
