Greetings Jesse_Pinkman,
I'm sorry to hear that the blue dot that the EVF on your EOS R6 Mark II is displaying is causing issues. It is odd that the blue dot goes away after a while but then comes back when you switch back to using the EVF. It is difficult to determine if this is a dead or stuck pixel without seeing a sample photo of the EVF to show what you are describing.
If you prefer to exchange the camera and if it was purchased directly from Canon USA, then you may reach out to our Sales Department for further assistance. They can be reached at 1-800-385-2155 from Monday through Friday between 9:00 am to 9:00 pm ET.
You may also send the camera to our service facility for repair if this is an option you are interested in.
Items purchased directly from Canon USA or from an Authorized Canon Dealer do include a one-year warranty if the item was purchased less than a year ago. You may view a list of Authorized Canon Dealers by clicking on the following link. I would recommend including a copy of your Proof of Purchase when sending in your item for the facility to review for any in-warranty service or repair.

Canon U.S.A., Inc. has created a new online repair portal that allows you to set up service in a few simple steps. The repair portal gives you the ability to set up service for multiple pieces of equipment at once, and to receive a repair estimate in the majority of cases, depending on your model and issue. The portal also allows you to upload images or videos that will assist us in repairing your product. You can also select how you wish to be notified of the progress of your repair. The portal's service history section allows you to view all services that have been performed on any of your camera or video products since January 7, 2020.
Please follow the link below to access our online repair portal to arrange for service:
