Does AWS Console have much that needs blocking? Seems a reasonable place to simply turn off uMatrix. You could also simply use a second browser with uBlock Origin for a limited number of sites - I tend to do that for a lot of checkout /payment options where the repeated reloads of whitelisting in uMatrix could be troublesome.
