Is there a way to add back the "Local Upgrade" feature for OnePlus devices

It's come to my attention in the process of trying to update my phone from Android 11 to A12 when I was rudely informed that T-Mobile has exclusive controls over my updates. I find that a violation of my rights to own the phone. I am paying it off and more than half way through it already. I'm not sure that paying it off fully would make much of a difference, but it doesn't hurt to ask. I want to be able to willfully update my phone as I please, as the OxygenOS updater gives me explicit permission from ONEPLUS THEMSELVES to help update my phone in a more timely manor, until I receive this notification;

 

"It looks like you're using a carrier locked device, so no updates for you. T-Mobile will do the updating from here on out"

 

Basically the short version, does unlocking the carrier help with this? Any tips, suggestions, and work arounds?

Anything will help

This has been beaten with a stick so many times.  If you want updates from the OEM's buy it from them.  If you have problems with the device ask the manufacturer, don't take carrier subsidies, and blame OEMs instead of carriers.  Due to the fact carriers get blamed for everything even if they had no control of the updates is the reason why there are delays.  If they are going to get blamed for things they have no control over they want to TEST updates against their security and network.  Fun fact updates still come from OnePlus after testing.

The difference between Apple and Android…  Apple takes all responsibility and they WANT you to go through them.  Android manufacturers love passing the buck to carriers.  Ironically if you go to Europe and Asia and the reason why they get updates quicker…  Is the fact they blame OEMs before they blame their carriers food for thought(I travel a lot for my line of work.)
