Can I edit a profile while it is active?

Yes, through Edit. Copying pauses while the change is saved and Copilink restarts the profile afterwards; copied orders that are already working stay in place. Ratio and Cross can only be changed in the editor; the card shows them but does not let you edit them there. The safest path is still to stop new leader activity, check broker exposure, disable the profile, edit it, then check it with one micro contract trade.
