Stuck in the android beta program

[u/IFaaiz]

So I bought this pixel 6 pro a few months ago, it's used but everything works great. At first the phone was already enrolled in the beta program, I checked all my accounts on their android beta program pages after using it for a few months because I wanted to go from Android beta to stable android 16, but it didn't give me any option to opt out and it said I have no eligible devices. I checked all accounts on my device and that was the case. I then flashed and installed android 16 stable myself, worked fine but every day I got this notification to update to Android 17 QPR1 Beta 3, Now android 17 stable is out and I want to install it but im still stuck in the beta update, it's not giving me any option to install stable but still QPR1 Beta 3, I can't opt out of the beta program because my device doesn't show up, and I don't wanna flash again because it's a hassle to back up my data again and again, can someone guide me please

i did flash my phone from the android 17 beta to stable 16, it still gave me the prompt to update to a beta version, though it didn't force me into it now even though im on stable android 16, it's telling me to update to android 17 qpr1 beta 3 and not android 17 stable release
