Is there any way to unlock local updates for andriod 13

It's beyond frustrating to find out well after the fact that your phones are locked down and you activity prevent your customers from using their phones how they please. I want to update to andriod 13, no one spends this kind of money on these devices to be using dates tech... If I wanted to stay on old versions of andriod I'd have bought a cheap phone or kept using an old phone. Does anyone know of a way to update your phone to a13, only in tech is it considered okay to restrict people's use of items they've purchased because you think its better for them. That would be like buying a new car that won't start if Ford thinks the weather isn't good enough to drive in, or your insurance company locking your vehicles ignition when rain starts, Nike sueing you or activity tampering with your shoes should you be discovered playing tennis in the basketball shoes. Just absurd you think this is a positive business model it's infuriating, I've been waiting ALL YEAR for the a13 update to move from manufacturer is working on it to your ridiculous testings phase, when we all know good and well there are os13 versions that have been out pretty much all year. Had I bought an unlocked model I would have what I wanted with my expensive phone yet I decided to purchase it from tmobile and instead I have to wait for your permission and testing regimine with id going to take what? another year? I will be thinking long an shard before purchasing any further phones with any company who follows this model of babysitting and restricting and trying to control how I use devices I've bought. That said if anyone knows of any way to update your phone, root, anything, please help!
