How to start Android and bypass the SIM PIN?

How to start Android and bypass the SIM PIN? I'm asking myself why it is not possible to start/boot Android without entering the PIN for the SIM card. The smartphone is a computer, with it's own authorization mechanism (device pin, finger print, ...) that I could easily use without access to the SIM and therefore the mobile network. (It is not about the screen lock pin). Why does Android not allow to start without this SIM card PIN and later enter the PIN? (E.g when I looked it up in my password manager in the phone)? I'm using a Google Pixel 4a - Android 13 (not rooted). I've not found a way in the settings about this. Is there any way (removing the SIM is not a real solution)? To add more context / explenation: - The smartphone is protected with the device PIN (or finger print, ...). This is required on "login" after a reboot or to remove the screen lock. - The SIM card is protected with the SIM PIN. This pin is required when the SIM functions are accessed - usually the smartphone keeps its authenticated access to the SIM functions once accessed for the first time as long as it is running. (This is not a permanent unlocking of the SIM, I don't know if this is even possible) - The problem is that on startup/boot of Android is accessing the SIM card forcing to enter the SIM PIN. This can not be skipped. This shall not be needed, as the Smartphone would work fine without the SIM as well (e.g. if physically removed).
