How do I add wifi printer to T-Mobile router WITHOUT the invasive data mining of the T-Life app?

iOS security is fine.  Apple is a data mining company and monopoly in their own right though.  There is a reason why GrapheneOS is the choice of Edward Snowden, Julian Assange, and others.  I don't care about needing that level of control over my device but I do want reasonable control over my device, including the apps on it, their permissions, etc.  With iOS, you have to jailbreak a device to remove a lot of the trash I don't allow on my devices and to have system level access to it.  If I own it.  I want to use it the way I want to.  Not the way Apple, Google, Microsoft, and other platforms think is what I need while making more money off of data mining everything I do on it.
