Yes. Even if you nominate someone else to make decisions for you (whether the power becomes effective immediately or upon disability), you still retain the power to overrule any decisions you wish. A power of attorney is not a guardianship and therefore you retain the right to make decisions which conflict with the agent you nominate assuming you have the legal capacity to do so.
Can I still make decisions if I have executed Powers of Attorney?
