You can't. The manufacturer already has a lot of backdoor in the firmware and binary blobs which are used even in LineageOS.

How do you evaluate a possibility manufacturer can leave some backdoor to do signature bypass using some private tool?
There are even specific attacks by the government to gain full access to your phone through the SIM. And every

The only way you could truly attain freedom is to use something like Librem 5 or Pine phone which is not great
for daily driver and are overpriced for the hardware they provide.
