Seems like a simple question; couldn't find the answer anywhere.
Conda should be kept up to date by doing

The conda deployed with ArcGIS Pro is a specially compiled/configured conda. You do not want to update it, or it will break other parts of the Pro Python deployment.
You don't... and if you are thinking of other updates... see
Timeline for python upgrade?
