How to request pin during boot process?

Hello, after reinstalling lineage os and assigning a pin, I always had to enter the pin when starting the smartphone. This is no longer the case with e/os. But I would like to activate this.

Does anyone know how to do this?

If I go to security in the settings and call up the pin settings, I can only lock the start screen, but unfortunately not the entire boot process.

Thank you in advance.
